interesting thoughts percival. Suffice to say they sound crack-induced...
anyway, my add to the mix.

Buying in short - to a point. If you're not totally comfortable or rolled for the stakes then I suggest buying in with 65-70% (i.e. $3.50ish for $5NL). Less than this you can't play real poker - 70% gives you enough room to actually do so (just)

As for the theory about about exponential-crazy-play-growth. Well, I've never seen it - but even if it happened, that would be a good thing for a solid player!
