Obviously it very much depends on the definition of "regular participant", but for the sake of the arguments let's define it as "someone who posts in the AC forum at least 10x per year" - the triple digit figure is quite accurate. If we include any FTer (even if the post count is zero) I'd estimate there are a few thousand FTers who read the AC forum somewhat regularly (let's say at least once a month).
However, the number of people who read / get their information from FT is substantially higher. At any given time the number of guests reading threads in a forum is substantially higher than the number of FTers.

I assumed you meant 98%-99% when you said "close to 100%" - which is very different from 95%.
Depending on which distribution function is used we'd roughly need anywhere from 80k - 160k flights taken by FTers to reach a >95% probability - and that still wouldn't include oddities such as most FTers boycotting Rouge flights (on the 763).
Maybe I would remember the exact calculations of the various distribution functions if the professor had used AC/FT as an example.
