Correct.
But old belives die hard

» » Eventually we can miss-use power.2TOST() ...
» » Then of course the question of the correlation parameter rho arises. How to choose?
» Not sure. Whereas two PK metrics are always correlated somehow, IMHO, here it may be different. One formulation doesn’t care how it behaves in relation to the other...

Sounds for me like rho=0 .
