Progression is the only way to win

[DoctorSudoku]

Theoretically speaking, the 0/00 should have the same negative effects for both the outside and inside bets.

I have real life experience with the baneful effects of the 0/00 on the outside bets (as per my recorded observations for winning versus losing sessions) and that's what I narrated above in my previous message.

I was thinking, maybe it's possible to play both sides using a progression so when an imbalance does occur it will create a profit.  Kind  of like 2 players at the table betting the opposite even bet with a progression...one will be winning big, while the other is losing.  Is it possible to create arbitrage here?  Any thoughts?

Scarface,
The biggest problem with betting on both sides simultaneously is that the zeros (when one of them appears) will kill both bets.

You can mitigate the effects of the appearance of the zeros somewhat  by doing "differential betting."

Progression doesnt change anything. If say you double up after losses, all you're doing is making separate bets on separate spins but wagering different amounts.

Double up after wins is the same as double up after loss,  the bet size increases but both don't change anything.
