Why isn't there a citation for this 90-100% number? I really am extremely curious where it comes from.

As for why I am posting a similar message (not nearly the same post, though) to you here as I did a year ago:

It is because I am very, very curious about where this number comes from and why there is no citation for it! It is fascinating to me.

(And, more generally, I have empirical experience with autofree that many users don't seem to have... so it seems useful to post about that experience to provide extra context for everyone else on this website).
