True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

Right, and one flattering data point from a group buy is not consistency.

Genuinely useful, thank you. I had the facts and not the framework.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. Pushing back on the anecdote-stacking. Twenty people reporting the same thing is twenty samples from the same self-selected pool, not twenty independent confirmations.

The figures, for anyone assembling their own picture. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful.
