Thanks for quik respond.
But I not quite understand how one more calculation can solve my question...
I do understand how to calculate things if they are same meausere in different categories, but I have different mesuars in rows.
In real data it would be 11 mesuares in 3 platforms = 33 rows.
And I just need % differentse in third columne, but i have to calculate this third cell in row independently for each mesure.
ps sample worcsheet added
The last thing I want to apply is to mark every calculated field in unifide manner: If difference less then zero - red, if it positive - green. Looking into heatmaps and additional calculated color measure (like there Conditionally Colored Cells ) but not accopleshed this yet. For now I mark entire 'platform' section, not only one row
