» If the irrelevant post hoc power is always 98%, I suspect a flaw in the software (or SAS macro).
» If it is always higher than the one used in sample size estimation it may be a miscalculation – ineradicably “popular” in Indian CROs (see this post). Revise your procedures

I'm sorry, I mean to say always it is coming in the interval 95 to 99 and some times 100 ofcourse one time only, some times we are getting less power on 80s but very less times.

A central lesson of science is that to understand complex issues
(or even simple ones), we must try to free our minds of dogma and
to guarantee the freedom to publish, to contradict, and to experiment.
