OK, here what I meant with my last posts and the gibberish code.



We have for instance 24 patients in a 2,2,3-BE trial, expected T/R being 1.0 and expected CV is 30%. This gives us a power of 0.87. Scaling preserves power. Thus should the variability be 50% and with preserved power we have 0.6983 as our lower acceptance range and 1.4320 as the upper. Wunderbar. This is the blue line, or shall we call it the EMA line.

I propose to check how the behavior is once the expected R/T diviates from 1.0 and being 0.95 (red), 0.90 (yellow) and 0.85 (green); these curves preserve the power within themselves but of course not between them. It was intended as a graphical illustration of the limitation of the EMA approximation when T/R differs from 1.0.

Note: We are now no longer so intimately connected with the original thread topic.
