Sort-of like Martingale
The system is dangerous simply because it often involves risking disproportionate amounts in relation to what you're trying to win while you attempt in those cases to recoup your losses and also collect the original to-win amount. In this way, it is like a Martingale system.
Now, with RPI, I don't see how Morrison could have even known the RPI for each team at the time each series was actually played, because it appears that old RPI info only represents teams as they stood after the final day of each respective regular season (but Morrison re-made the win-loss records, going five years back, only late last summer after the baseball had been losing money).
In basketball, buying points makes things more expensive than in a traditional Martingale system. And the points aren't even normally needed. But how do you know when they will or won't be?
The safest way to play his system is if you can make sure that a lost C Bet won't devastate your bankroll. Basically, a lost series will cost you roughly eighteen times, more or less, what you're initially trying to win on Bet A. Therefore, it's probably best to just stick with a to-win amount of around one percent for bet A. You may get by with risking much more for a long time, and this can profit you well, but one loss could then possibly destroy you. It's a matter of how high you want to raise the stakes. The systems have lately performed well, but new losses are always within the realm of possibilities.
By the way, does anyone know what it is behind Morrison's claim that the new v2 MLB system has an ingenious catch that will allow a person to determine when one team will totally annihilate another before the game even starts? It can't be just that he's taking the run line when he bets the underdogs, because the old system already does that.
Also, in his marketing e-mails, he has called the old system "flawed and outdated." Since I haven't been lucky enough to profit with him yet, I'm not anxious to give him the extra money right now in order to find out what's going on with these claims about the old and new v2 MLB systems. Does anyone know?
