I think it's a good theory, but to me it doesn't seem like you will be able to win a lot of money in that rule.
But then again if you just want to pay some bills and buy some extras it good be a good rule.
I just think you'd have to be really patient in freerolls and I'm not that patient.
But its a good rule for me and others with not much free money in this economy so thanks for that.
