... $17 per 100 is terrible when you concider your max bet.. .
Or, make twice that an hour playing the same game with the same max bet with a lot less ROR.
Anyway, I think CVdata does actual sims and generates a huge amount of info about it where as CVCX has a lot of canned sims and you can enter your own variations and it spits out some basic info that can be useful for comparison purposes. CVData may not generate optimal bet ramps, not sure.
Could be way off here since, like I said, I don't have either.
