Thanks again, Helmut, for sharing your wisdom so quickly and in details.

Since the alternative is based on T1 = R OR T2 = R, I am attempted to think that a larger sample size is required for the alternative T1 = R AND T2 = R. Is that indeed the case? If so, would you have any recommendation on how to approach the sample size estimation?

Thanks again, I very much appreciate your help!
