Multiple conditions finding median in Excel - excel

I have included a link to a sample sheet. It contains home sales for 17 years and includes the property type (Type), price (SP), Value (Price/SQF), and Size (SQF). I want to find the median of each for every type, for every year, and for every month.

I used this formula (for example) for finding the median value each year, but when I manually check it, it is incorrect: {=AGGREGATE(17,6,Value/((YEAR(Closing_Date)=$J127)*(Type="Condo")),2)}.
I really don't understand how that formula works (specifically, the "17,6" and the "2" at the end). I've tried using the =median with all the conditions but I get missing argument errors. Not sure what to do.
I've included space and allow editing of the test file if that helps. Once I see the formulas for one property type, I'll be able to replicate for the other 2 types.

{=AGGREGATE(17,6,Value/((YEAR(Closing_Date)=$J127)*(Type="Condo")),2)} is the right answer. After studying quartile.inc I realized I had a different error that was the causing the problem.

VLOOKUP function not returning correct value, Index Match also incorrect. User Error?

Working in Excel 2019. In the same realm as one of my previous questions, I'm working with a database that I'm trying to look through via functions to get my values. The VLOOKUP tool worked well for going through the time-table to find the value I need, but it's not working when I'm trying to find RPM as the look-up value. Here's the gist of the data.
We have Time(sec, A:A in "PPT_156Data" sheet), RPM (B:B in same sheet), and Pressure (Bar, C:C in same sheet).
From the graph, you can see that we ramp to 8000RPM over the course of around 60 seconds, and then ramp down to 0RPM over the next 30. Test times WILL vary and rates WILL vary from pump-to-pump, as each one will give different data values based on the pump. That's why, say, 1000RPM will not be in the same spot every time.
I'm trying to find the RPM at 1000 intervals up to 8000 and report out the pressure at said intervals.
Here's what I tried so far, with imagery as well.
'Disregard if you see W25 for S25, I had just been trying multiple things
First, I attempted the same VLOOKUP code I had done for the time-table prior
=VLOOKUP(S25,PPT156_Data!B:C,2,TRUE) 'S25 being lookup value
This worked fine, UP UNTIL it hit a particular spot. For some reason, as soon as it tries to find an approximate match for 6663RPM, it faults out and gives incorrect data. From then on, all the way to 8000RPM, it will ONLY give the result of 0.139BAR. I have no clue why. Trying to find that value in the return array gives multiple results, but it's not like it's the ONLY value left.
So, I tried to do a wildcard for it with the following code
=VLOOKUP("*"&S25&"*",PPT156_Data!B:C,2,FALSE) 'Attempted both False and True states
Gave N/A for both of the values. Not sure if I'm entering in the wildcard incorrectly here. The decimal places that the RPM can go to ranges between 2-5 (hundredths to hundred-thousandths, IE 7000.00750)
I then thought maybe an Index Match would work.
=INDEX(PPT156_Data!B:C,MATCH(S25,PPT156_Data!B:B,-1),2)
Tried that in wildcard format too, returned nothing. So, I decided to see if I could even match a value for RPM with the following attempts
=MATCH(S25,PPT_Data156!B:B,-1)
This gave nothing. HOWEVER, when setting the match specification to 1, it gives the very last row in the data set. So, I decided to find a value in column B, and attempt to match with it exactly.
=MATCH(7000.07,PPT_Data156!B:B,0)
This also returned nothing. Even though, you can see in my images, that the value is ABSOLUTELY there. SIGFIG shows it's 7000.1 but trust me, it's 7000.07. So that sort of threw me for a loop. Figuring maybe there was a different error and grasping at straws, tried another Index Match formula, this time subtracting the lookup value in an attempt to get it extremely close and absolute value/min it
=INDEX(PPT156_Data!C:C,MATCH(MIN(ABS(PPT156_Data!B:B-S25)),ABS(PPT156_Data!B:B-S25),1))
I'm at a loss. I'm not sure if because the rate ramps up and down, thus not being in ascending order, is causing a problem? I can't change that. I am thinking I may need to create a macro for this in some way? Maybe a helper table? But I can't even FIND the match value to create a helper table. Any help at all would be VERY appreciative.
Thank you for your time looking at my post.
I am presuming that you want the first pressure reading when the RPM hits above each 1000 interval. I got to a solution but feels a bit complex.
=index(C:C,1/max(iferror(1/(row(B:B)*(B:B>E12)),Null)))
Breaking this down, we create a boolean array where the RPM hits above the interval
=B:B>E12
and then we multiple this by the array of the rows of column B
row(B:B)*(B:B>E12)
which gives us an array of the row numbers when the RPM is above E12 but also zero for all the ones that do not.
=iferror(1/(row(B:B)*(B:B>E12)),Null)
We then force an error with the zeros by dividing and replace with null. We get the max since we inverse the row numbers and then inverse again to get the row number back.
=index(C:C,1/max(iferror(1/(row(B:B)*(B:B>E12)),Null)))

How to identified the smaller number only from specific lines of a table

I am not familiar with excel as you can probaly guess by my question so I am sorry if it's a silly question but I have been googling for a long time and I can't do it.
I manage to do it in excel 365 with the function filter, but I can't on excel 2019 (I am required to do it in excel 2019)
I want to identifed the smaller number of a specific combination of cells using two table.
Table1 has name of people and places as well as a number. (the number shows the difference of the last time a person went to a place and the [in months])
(In this project the inspector cannot go to the same place twice unless 4 months have pass, thus why I want the smaller number, using the date of the last visited and the fcuntion now I get teh number of months that have pass)
Table2 has only the name of one person out of these people but has the name of all places. I want to get the smaller number for every place.
This is my table1: (I hided other peoples names so I can show a more compact examlplo)
And this is my table2:
I thought that I could use a function aggregate with a function if inside of it to get only the values that I desire.
It did not worked thou. Was I had miss undertand the fact that function if only gives me true or false. But thought that the aggregate function could wordk. It did not as well
=AGGREGATE(5;3;A2&B2=Table1[#Place]&Table1[#name];1).
overall my question could be summarize to which funtion should I used?
Which function should I use?
obs: In excel 365 I used concat to make a code an thus only used one cell, but I don't see why it wouldn't work if I just select two cells insted of one (teh concat cell)

Excel Formula Slow

is there anything i can do to further improve performance of this formula ?
=IF($A3<>"",IF(Jan!$E6<>"",LET(d_patt,IF(Jan!$E6<>"",VLOOKUP(Jan!$E6,SETTINGS!$A$12:$B$27,2,FALSE)&IF(Jan!$B6<>"",Jan!$B6,0)&IF(Jan!$C6<>"",Jan!$C6,0)&IF(Jan!$D6<>"",Jan!$D6,0),""),"ROT"&IF(LEN(Teams!$BHR4)>0,MID(Teams!$BHR4,MOD(NETWORKDAYS.INTL(Teams!$C4,I$2,"0000000")-1,LEN(Teams!$BHR4)/3)*3+1,3),"000")&IF(LEFT(d_patt,3)="OVT",d_patt,"OVT000")&IF(LEFT(d_patt,3)="SSI",d_patt,"SSI000")&IF(LEFT(d_patt,3)="SSO",d_patt,"SSO000")&IF(LEFT(d_patt,3)="SDS",d_patt,"SDS000")&IF(LEFT(d_patt,3)="HOL",d_patt,"HOL000")&IF(LEFT(d_patt,3)="LID",d_patt,"LID000")&IF(LEFT(d_patt,3)="UNP",d_patt,"UNP000")&IF(LEFT(d_patt,3)="FLD",d_patt,"FLD000")&IF(LEFT(d_patt,3)="MAT",d_patt,"MAT000")&IF(LEFT(d_patt,3)="LIS",d_patt,"LIS000")&IF(LEFT(d_patt,3)="CBR",d_patt,"CBR000")&IF(LEFT(d_patt,3)="ABS",d_patt,"ABS000")),"ROT"&IF(LEN(Teams!$BHR4)>0,MID(Teams!$BHR4,MOD(NETWORKDAYS.INTL(Teams!$C4,I$2,"0000000")-1,LEN(Teams!$BHR4)/3)*3+1,3),"000")&"OVT000SSI000SSO000SDS000HOL000LID000UNP000FLD000MAT000LIS000CBR000ABS000"),"")
i have this on a sheet for each day of the year x 400 people so 146k+ times. this is therefor taken up 80% of the sheet load time.
The sheet basically gets shift patters from Teams, check if there is any holidays, overtime etc from the relevant month tab and relevant cell for the day, and then will generate a code like below.
ROT080OVT000SSI000SSO000SDS234HOL000LID000UNP000FLD000MAT000LIS000CBR000ABS000
i have so far managed to make this faster by using the LET function, but not show if its possible to make any further improvements.
if you need an example file i can send this or upload somewhere, not sure if that is possible via stackoverflow or a preferred site to upload to.
Thanks
The following is a shortened version of your formula to reduce the complexity of computations.
Instead of building the 'OVT000SSI000...' string one piece after another while always checking if the first 3 characters of 'd_patt' match the current piece, we can set the whole string with '000's as default and only replace the section that matches 'd_patt' (see highlighted elements in screenshot below)
Which results in the full formula:
=IF(LEN($A3)>0,"ROT"&IF(LEN(Teams!$BHR4)>0,MID(Teams!$BHR4,MOD(NETWORKDAYS.INTL(Teams!$C4,I$2,"0000000")-1,LEN(Teams!$BHR4)/3)*3+1,3),"000")&LET(default,"OVT000SSI000SSO000SDS000HOL000LID000UNP000FLD000MAT000LIS000CBR000ABS000",d_patt,VLOOKUP(Jan!$E6,SETTINGS!$A$12:$B$27,2,FALSE)&IF(LEN(Jan!$B6)>0,Jan!$B6,0)&IF(LEN(Jan!$C6)>0,Jan!$C6,0)&IF(LEN(Jan!$D6)>0,Jan!$D6,0),IF(LEN(d_patt)>0,REPLACE(default,SEARCH(LEFT(d_patt,3),default),6,d_patt),default)),“”)
If $B6, $C6 and $D6 can only be either empty or a numerical number, in other words, if they are never a letter or special character, the 'd_patt' function can be further shortened as follows:
Which results in the full formula:
=IF(LEN($A3)>0,"ROT"&IF(LEN(Teams!$BHR4)>0,MID(Teams!$BHR4,MOD(NETWORKDAYS.INTL(Teams!$C4,I$2,"0000000")-1,LEN(Teams!$BHR4)/3)*3+1,3),"000")&LET(default,"OVT000SSI000SSO000SDS000HOL000LID000UNP000FLD000MAT000LIS000CBR000ABS000",d_patt,VLOOKUP(Jan!$E6,SETTINGS!$A$12:$B$27,2,FALSE)&(Jan!$B6+0)&(Jan!$C6+0)&(Jan!$D6+0),IF(LEN(d_patt)>0,REPLACE(default,SEARCH(LEFT(d_patt,3),default),6,d_patt),default)),“”)

Summing Elapsed Time Based on Two Criteria - Excel

Like the title says, I'm trying to sum elapsed time based on two criteria in Excel (2016). Specifically the elapsed time of a phone call based on user and call type, examples below.
The actual data is similar to this Dummy Data Set where there would be a list of users, Full name, the duration of a given call, Duration, and the type of call, Call Type.
The expected output would be in this format; however, the main focus for my issue falls under the Total Time column, and its worth noting that the red times shown were hand-done as these are the cause of this post.
As for the logic I'm using at the moment to try and get these results, it's =SUMIFS(C2:C16, B2:B16, G2, D2:D16, H2&"*") where C2"C16 is the Duration column, B2:B16 is the Full Name column, G2 is "Generic User", D2:D16 is Call Type, and H2&"" comes to Local, worth a note is the wildcard, as there are two types of Internal and Local calls, but I'm just trying to get all Local and all Internal without distinction of sub-types.
Additional notes for the cell formats are that the Duration and Total Time columns are set for [h]:mm:ss, but I've also tried other time and number formats which didn't change the outcome.
So at this point I'm just spinning my wheels as I've Googled and looked into different ways to go about this, such as different cell formats, cell operations/logic and so on, and I'm just unsure where the issue may actually be, so any suggestions or help would be very appreciated.
Edit 1: Including a link for the file

=SUMPRODUCT((B$2:B$16=G$2)*(C$2:C$16)*ISNUMBER(FIND(H2,D$2:D$16)))

Has anybody encountered strange behavior of LOOKUP()?

NOTE: I don't need a solution for the actual problem to be solved with Excel. I want to understand and discuss the behaviour. And I want to see, if other people can reproduce the situation and make them aware of it.
Situation is extremely simplified for debugging the problem.
I use Excel 2007 in an cooperate environment
In a calculation made on a two-week basis, I have to fill in numbers for the two-week interval that are valid a whole month. For example first two weeks of December I have to use value 12, second two weeks again, than first to weeks of January I have to use 1, second two weeks again.
Therefore I have a column for each two-week period with a field of current month (green area in screenshot). The values valid for the month are in a second table (red area). To retrieve the value for current period, I use a LOOKUP()call:
(A2): =LOOKUP(A1;$A$9:$H$9;$A$10:$H$10)
...
(P2): =LOOKUP(P1;$A$9:$H$9;$A$10:$H$10)
As you can see in the screenshot, the function goes havoc and retrieves false values.
For testing, I reproduced the situation with the international phonetic alphabet instead of month names. Therefore:
(A5): =LOOKUP(A4;$A$12:$H$12;$A$13:$H$13)
...
This time, the function works well. Therefore I guess, it has something to do with the name of months. Maybe they have some internal representation, despite the fact, the cell are formatted as "text".
I already tested vertical vectors instead of horizontals in the red area. They lead to the same situation.
NOTE:
I finally solved the original problem by using HLOOKUP() and VLOOKUP(). There I found another clue. Both show the same behaviour if [not_exact_match] is committed or set to true but work fine, if exact_match is enforced. So, how can Februar be an approximate match to Dezember?
See http://office.microsoft.com/en-gb/excel-help/lookup-function-HP010342671.aspx
For the LOOKUP function to work correctly, the data being looked up must be sorted in ascending order.
This is not the case with the texts "Dezember", "Januar", "Februar", ...
If you would use real dates 01.12.2013, 01.01.2014, 01.02.2014, ... and format them as "MMMM", then it should work. Of course the lookup_value also has to be in that form.
Same problem with VLOOKUP and not exact match. http://office.microsoft.com/en-gb/excel-help/vlookup-function-HP010343011.aspx
If range_lookup is either TRUE or is omitted, the values in the first column of table_array must be placed in ascending sort order; otherwise, VLOOKUP might not return the correct value.
