The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either.

Fair, and it stops being fair at the extremes. The middle of the range is well understood; the ends are where the honest answer is that nobody knows.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Adding it to my notes with a link back to this thread.

I read this differently from VendorMark, on substance rather than tone. Pushing back on the consensus forming here. Consistency is not the same as correctness, and a board that agrees with itself quickly is usually agreeing with the first person who sounded certain.

Adding the numbers, since they settle part of this. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
