I believe you looked for this thread:
AQo on the Button, am I right?
The info you provide is good and correct. I tend to fall to this trap occasionally when multitabling.
However, for those of us that might have short attention spans a more useful info would be e.g. that after how many hands does vpip, pfr, stats are accurate enough to be X +1 or X-1 % with say 95% reliability. Or that how reliable these are after e.g. 50, 100, 500 hands. I'm not asking you to calculate these nor am I competent to do that myself either.
The short-handed limit book of Borer, Mak and Tanenbaum quotes 200 hands for vpip and pfr to be "reliable" to some extent.
I'm pretty sure there's a thread here somewhere that discusses these. I don't have time to search for these now. If some of the older hands happens to remember a few good threads I'd be delighted if you take the time to post links to them here.
