Hi Outlaw Torn, Hi Great Maestro,

❝ ... Power is based on assumptions. If those assumptions are wrong (like the point estimate, the variability) then that is an issue. So perhaps you'd be revising your assumptions when you do power/Sample size for the next trial.

And this is not post hoc power but ad hoc power/sample size estimation as always necessary in the design step of a study.
