V.&F. said they determined KC by simulation and that it depends almost entirely on number of decks, for any rule set. I assume that Norm would have done the same for his reKO bet schedules, without naming the point at which the bet is raised.

Not quite clear here. Wouldn't you have to add 4 in the above formula to make the RC=TC?
