The only way WGT will make any corrections is if people stop paying money to play this game.
As well, we seem to have a few players who say everything is fine - either they have found a way to circumvent WGT's built in variances, they are extremely lucky (and they should be buying some lottery tickets) or they are not being very truthful)
In any event, it is not likely that:
1) WGT will fix the errors
2) that people will stop spending money on this game.
