I guess it would depend on what you're trying to report on. I took a look at your charts and your comment about averages in the initial post which threw me off when the charges were totaling the turnover rates but I think I see what you're doing.
I'm just looking at the above of what you were trying to do now - and one issue would be that you're doing a total sum in the numerator but the average in the denominator. You can go either way but you should be consistent in either doing the totals for both or average for both and see how that looks. So either:
([# of FT Separations]+[# of PTR Separations]+[# of PT Separations])/([# of FT] + [# of PTR] + [# of PT])
or
Average([# of FT Separations],[# of PTR Separations],[# of PT Separations])/Average([# of FT] ,[# of PTR] ,[# of PT])
Depending on how your other values are being derived (either as a % or a number) you may have to multiply by 100 to bring it in line with the other values. It might be best to do the calculation and then list it in the table report to see how it looks - if your main ratios are all whole numbers where as the new one is a tiny decimal - you might just need to convert it from a percent so it reports properly.
