Your p25 employee is probably much closer to your p95 employee than to the p50 "standard" human, so yeah, I think you have a point there.

But at least in food prep, p25 would already be pretty damn hard to achieve. That's a hell of a lot of autonomy and accuracy (at least in my restaurant kitchen experience which is admittedly just one year in "fine dining"-ish kitchens).

I'd say the p25 of software or SRE folks I've worked with is also a pretty high bar to hit, too, but maybe I've been lucky.
