At Stake's in-house Black Jack, a dealt hand can have up to 2 bets if you split or double (you can't double after split).
If you won a Black Jack, you win 1,5 bets and not 1.
At brick and mortar casinos, you can split multiple times and after split you can also double, so it is possible that you made 10 bets in a dealt hand.
Do you have prove Stake calculates a double and split as 2 bets? and a won Blackjack as 1,5 bet?
