Westley, I think that by checkraising the turn you will be forcing worse hands to fold that would have called down if you bet the turn.

I don't think that you take take much away from Westley's numerical analysis. Since the villian will be folding much more often to a turn checkraise than to a turn bet, the payoff stuctures are different. The 3.9 vs. 4.4 has too small a difference to make up for the assumptions that Westley has made.
