Adding the numbers, since they settle part of this. For anyone reading later: the numbers in this thread are worth checking against a primary source before you act on them, including mine. Half the figures circulating in this community trace back to a secondary summary that dropped a qualifier.
If somebody has the primary source to hand I would rather cite it than paraphrase it.
Closing the loop on my own question.
Update: the thing I was blaming turned out not to be the cause. Leaving the original post as written rather than editing it, so the mistake stays visible for whoever searches this next.
Found this through search years later and it is still the best discussion of the question, so adding one thing. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.

That is right for the common case. Whether it is right for the case being asked about depends on a detail that has not been given.
