If it really is betting on 50/50 events, then you can expect that over the long run you will have approximately the same amount of money as you started with, so what is the point of the system in the first place, when you just end up with approximately the same amount you started with. Also, though your system shows positive results now, the sample size is very small, so it should even out eventually.
You're right, but if the system is good enough to stay above 55%, you do 1.5X every month, betting at least 3 games per day on average
I see this thread since April and you have only posted 4 games in total with 50% winrate. We need a lot more statistics than those to tell if your system really works in the long time or it does not. However I want to agree with your points on how to manage your bankroll and to place those kind of bets (except the odd , the user decides and should not be forced 1.8 and up) and such bankroll management can save many avid gamblers from pure misery in the long run.
Yes we're only at 4 bets, it's hard for me to check bets manually, furthermore when MLB plays is 3 a.m for me in Italy.
The data i need for the script is encrypted, but i will solve this problem.
