Thanks John: you are correct! the answer to your question is that I used a factor 0.5 in that equation {H1}. and that does not belong there as is evident in the source FDA Guidance. It is the other two parameters that are modified by the 0.5 multiplier.

Now your data checks out on my spreadsheet, since as you say the final value is

0.07358

The Phoenix calculation of WT was done on an adhoc basis by modifying the existing code (WR). What should be done is that workflow(S) should be created such that both WT and WR can be obtained from the same workflow or workflows. That way you do not need to modify the WR code each time you need WT as well as WR. After it is very relevant to have a comparison of WT and WR when comparing two formulations.

Therefore my spreadsheet now validates your calculations and I have corrected it.
