Conditions were
6 Decks, S17, DA2, DAS, ENHC, No surrender,pen 4-5,2/6
Estimated House Edge for these rules: 0.55%
we used 1:20 spread.I used count system 2210000-1-1-1
best correlation against Snyder u/o report.

Always when count was high i saw dealer picture and he made 20 several timessu main bets lose.u/o was normal.
Sometimes some moron took first 2 box.Count was high..
the moron got with min bet 2 high,my 5 box 2 win

What was wrong?According to snyder book my edge should be monster when im using 1:20 spread
