Beating Bonuses has a thread about beating the new 32Red SUB (and presumably the monthly reloads).
It seems CS are giving conflicting information, and the "advantage" advice is to find a CS that gives you the "right answer", keep a record, and then play.
Is this what has happened here?
Find CS who says each seat on multihand counts as a separate bet, then play. Not keeping a record might be where the OP slipped up, which is why he has resorted to using another player's chat log to prove his case.
The 32Red term ALREADY clarifies the situation for multi hand games, and this is that a DEALER dealt hand is what counts, so the 25% is the accumulation of ALL bets over ALL seats played.
As for doubles & splits, I DON'T think these should count, since they are conditional bets, and the player has no way of knowing whether one is needed until the hands are dealt. Additionally, NOT splitting when appropriate can place the player at a disadvantage. Doubling, however, is debatable, since NOT doubling does NOT affect the chance of the player winning - so maybe ONLY splits should be allowed, and not penalised.
Again - WHY CAN'T THIS BE SORTED THROUGH SOFTWARE ENFORCEMENT, this would end this kind of argument, even if players DIDN'T read or understand the max bet rule.
