Welcome Keith!
I agree with Bill in that your "pass' guidelines are pretty much the Methodologies guidelines as well.
I can offer one more and that was taken from a day that Doc and Aline were at Santa Anita wagercapping the races:
They came upon a race where there was this horse that was being bet very strongly and they both could find absolutely no reason for it. They decided to pass the race because they did not have a complete "understanding:" of what was going on. I read that Peter Tolan also would not play races that he felt he didn't understand fully.
Anyway a bit of food for thought and again welcome to Pace and Cap!
