Thank you for this!

In comparing the correlations of the Hi-Lo I18 to my column 3 on p. 62 of BJA3, I was pleased to see not one number off by more than 0.01, and many exact. Since I did my work for four decks, 23 years ago, and with a pocket calculator, needless to say, I'm happy.

Less perfect are the Fab 4, especially two of the four. Unfortunately, Griffin did not have EORs for surrender, and I relied on data from Steve Jacobs, some 11 years later, to generate those values. Obviously, he made some errors. If there is ever a BJA4, I will have to make corrections.
