I just found out that I'm headed back to Georgia, so I am updating my databases to take another run at your Cash 3. Anyway, when I ran a test of my back-check program on your numbers, the program basically did that old pinball machine TILT! thing on the number 998. It turns out that 998 really is kind of interesting for tonight's Cash 3. Not only does 998 have a ton of back-check hits, but it has a double one-hop back-check which I have charted below in case anybody is interested.

P.S. In the course of my workup, I found that 998 and 818 met a separate test that I ran, however 818 was otherwise completely lackluster. I might put .50 on it JIK.
