## About GMR 1.10 [Power / Sample Size]

» In this case, why they assume GMR=1.10 instead of the "normal" 0.95/1.05.

Yes. This was an example what i was trying to give to Helmut & Elmaestro. This is a very rare case, but in General GMR would be taken as 0.95/1.05 as you said, but the power remains same as 95% to 99%
