Hi-Opt II with full indices has PE = 0.639.
I think this analysis raises as many questions as it answers. For example, these more accurate calculations of playing efficiency are lower than the approximations given by Griffin (see Chapter 4 in the reference below). There are several possible reasons for the difference: is the approximation inherently biased, or is it simply due to different assumed number of decks, penetration, etc.? "

Don, what you think ?
I think the latter. People just throw out PEs without ever giving the rules and conditions. Obviously, they matter.
