Yes. I agree. I got rushed this morning and probably should have deleted that post instead of posting it.

Taking it from the perspective of Villain's standard raise sizing (or Hero's when Hero is BTN):

When BTN limps, there is no bet to Hero. (not really a bluff, then, eh?)
BB continues with 100%, obv.

BTN min-raises: 1.5/(1.5 + 1.5) = 50%
BB continues with at least 50% range.

BTN raises to 2.5bb: 2/(2 + 1.5) = 57%
BB continues with at least 43% range.

BTN raises to 3bb: 2.5/(2.5 + 1.5) = 63%
BB continues with at least 37% range.

BTN raises to 4bb: 3.5/(3.5 + 1.5) = 70%
BB continues with at least 30% range.

Those are always "at least" due to the fact that when BB continues with exactly that amount, it is a 0 EV bet for BTN, even if BTN just check/folds on all post-flop hands.
