Sorry, didn't mean to ignore you.

I tended to leave folks who posted on only a few threads off of the calculations, since the results wouldn't be very meaningful. For instance, a person who posted to only ten threads (1%), but got very involved in those discussions, might have a PPT of 10 or more, but that wouldn't have the same meaning as a person who routinely posted in (say) 20% of the threads with the same PPT.

However, since you asked, by my calculations:

HigherFlyer = 1.5% @ 7.0 ppt
