 It was not until recently that I came to realize why when I changed books
 the Crafty I ran on ICC always dropped in rating points sometimes
 significantly. I had forgot to do the points you just made. And as a result
 Crafty had zero in book learning. A couple of years ago I couldn't pass
 kindergarden when it came to understanding what makes Crafty tick
 today I feel I've enrolled in the first grade. :,)
