Believe it or not, I did something like that since I started with JM in April. I won all the bets (30) but I made conservative bets: win about 100$ on A, 50$ on B and break even on C (actually I skipped the last C bet with TOR so I go burned). I joined this forum about a week ago, so I didn't know about your system. I will start using it today with small amounts hoping I can get back what I lost lately with FLA @ WAS and CIN @ SF.
GL everyone!
