Is there a way to determine the top 80% of a list using multiple conditions

[TheNoocH]

Here's a quick example...sorry for the formatting...but I don't have the tools to post html sheets...if someone could point me to what is being used these days i'll add it

but essentially i'm trying to figure out if Running Value is top 80% of all values based upon the multiple criteria
i added 2 helper columns to show logic of what trying to do and included what i would expect in the Top 80% column...
any help would be great...thanks


Criteria1 Criteria2 Criteria3 Value SubGroup % of sub Top 80%
1 A X 100 170 58.82% Y
1 A X 50 170 29.41% Y
1 A X 20 170 11.76% N
1 B X 50 50 100.00% Y
1 C X 100 100 100.00% Y
1 C Y 50 80 62.50% Y
1 C Y 20 80 25.00% Y
1 C Y 10 80 12.50% N
2 A Z 100 250 40.00% Y
2 A Z 50 250 20.00% Y
2 A Z 40 250 16.00% Y
2 A Z 30 250 12.00% Y
2 A Z 20 250 8.00% N
2 A Z 10 250 4.00% N

I used this array formula in G2 copied down and got the same results you showed

=IF(F2>=PERCENTILE(IF(A$2:A$15=A2,IF(B$2:B$15=B2,IF(C$2:C$15=C2,F$2:F$15))),0.2),"Y","N")

confirm with CTRL+SHIFT+ENTER
