i dont know man
i cant look at that chart i just posted and not see a grail......
The only problem with this system is that it lends itself to bad luck hitting you like a sledgehammer......I'm willing to bet there's a less risky progression that's still effective.
Having said that.......I do think that the bet selection might be the best we have available without some serious tracking, so with a bit of luck, you might be able to turn this into a winner long term!
