The passage around this formula
…two prompt versions is sampling noise, not signal. Teams that cannot afford several hundred repeated trials on every task for every change — nearly all of them — have exactly two disciplined options: accept a larger before declaring a regression, watching for a trend across several consecutive merges rather than a single run, or concentrate the expensive repeated-trial budget on the smaller set of tasks where a regression would be most costly and accept thinner evidence everywhere else.
