Find percentage of last 10 weeks

I would like to find the winning percentage of the last 10 weeks with various criteria.

In the attached workbook... The result would be placed in RESULTS F28-F34. As an example, I want to find the winning percentage of PMH over the last 10 weeks. In the prev column, I have the formula to calculate the winning percentage of all results per setup. All data is in the sheet DATA.

Try

=IFERROR(COUNTIFS(Table1[SETUP],B28,Table1[G/L],">=0",Table1[WEEK],">="&MAX(Table1[WEEK])-9)/COUNTIFS(Table1[SETUP],B28,Table1[WEEK],">="&MAX(Table1[WEEK])-9),"")

I would amend your formulae to reference B28 etc rather than hard-coding the text such as "PMH"
