Some may be trying to bash, others are not and trying to offer suggestions or warnings. I think you've thought this through for the most part. Variations of this type of system have been thought of and attempted by every gambler in the free world. Most people when they first get into sports betting have that same thought..."Why cant I just double up when I lose on a good team until they win?" I know thats not what you're doing, but you are doing a variation of it. Answer: Because every team in every sport goes on losing streaks, no matter how good or bad.
Indians lost 2 to the Royals. The White Sox, Yankees, Red Sox, Mets, etc will all have cold streaks at some point this year. Some team will get swept right when you have doubled up on them. Your record will end up being 22-8, but you might be losing overall.
The closer we get to the middle of the season, the closer we get to having good teams have let ups, let downs, etc. The Cubs had one today vs. the Marlins but bailed themselves out in the end.
I think that 80% of the posters on this board have lost their ass at some point of their gambling careers doing something like this. It's almost like a requirement. I think that every game that passes that you win, you should consider stopping, or at least cutting units in half or something. We've all been in your shoes before.
If you have a method for selecting teams, and not just picking favorites blindly, this may have better success. Whatever your system is, I wish you the best with it, and you'll never hear an I told you so from me. Later.
