Conditional formatting on top 3 values from each row in matrix visual

Hi, lets say you have produced a table with the columns location, time and qty. Then you can either create a measure or a calculated column for this table. Here I take a calculated column and the top 2 values

IsTop2 = 
var loc = TestTable[Location]
var thisQty = TestTable[Qty]
var ct = CALCULATE(count(TestTable[Qty]), FILTER(TestTable, TestTable[Location] = loc && TestTable[Qty] > thisQty))

return 
if(ct < 2, "#009292", blank())

 You then use the conditional formatting menu and select format by field and reference the IsTop2 field. 
This highlights for example the background of the top 2 in some hex color as above. 
I produced a table that will already shows the pivot values of the visual. The surely can be modified, but the principle should be the same.

Best regards
