It’s a general question I ask of everyone who claims they are 10x more productive. Year/month/day/hour doesn’t matter. Did you do 10 days of work yesterday? 10 weeks of work last week?

It is actually a very forgiving metric over a year because it is measuring only your own productivity relative to your personal trend. That includes vacation time and sick time, so the year smooths over all the variation.

Maybe he did do 5 weeks of work in 1 week, and I’ll accept that (a much more modest claim than the usual 10-100x claimed multiplier).

Yeah, but he gave you an affirmative answer, that it did make him more productive, and you keep moving the goalposts as I watch.

Not only that, I think you're misrepresenting his claim:

> I suspect I’m likely 5-10x more productive, though it depends exactly what I’m working on

1) He didn't say 10-100x

2) He said it depended on the work he was doing

Those seem reasonable enough that I can take his experience at face value.

This isn't about you pressure testing his claim, this is about you just being unwilling to believe his experience because it doesn't fit the narrative you've already got in your head.
