Right, and the exception is worth naming rather than left implied, because the exception is where people get into trouble.

That is the short version; the long version is somebody else's post.

Saving this. It is the first explanation that did not require me to already understand it. I will report back once I have actually tried it.

I read this differently. The confidence in this thread is running ahead of the evidence, and I would rather the uncertainty were stated than smoothed over because it is unsatisfying.

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.
