Hi Helmut,
Thanks again for this explanation.

After some thoughts, I am wondering if the sample size estimation only considers one comparison. I found an old following post regarding this topic.

If we are considering both T1=R and T2=R, perhaps, we need to look at the bivariate distribution of the two test statistics when looking at the power. And these should be correlated as well, which makes things complicated. I am maybe missing something and was wondering if you could enlighten me on this subject.

Thank you sincerely!
