SparJMU, I understand where you're coming from. Under certain circumstances there is the possibility for very large losses using this system. We've talked about this in the discussion thread and have a plan if we face the worst possible situation.
The level of risk is so great because the elevation of bet size after a loss is exponential and is further compounded by large odds, -160 or higher especially. If betting on a favorite, a B-bet is more than double what the A-bet was and a C-bet is more than double the B-bet. The most dangerous situation is when a heavy favorite loses the first 2 games of a series. Depending on your initial bet size you could be risking $1000 or more to profit $100 in game 3.
Instead of solely relying on the money line for a C-bet, we'll use the -1 run line or a simulated one if not available at particular sportsbooks. This will help lower the amount at risk and allow the possibility of a push.
It's also very important to practice good money management. Personally I would recommend betting to win no more than 2% of ones bankroll on an A-bet for this system. stingyrivers is betting 5% on A-bets which is far too much IMO, but that is his choice. He's not encouraging others to do the same.
If you have further inquiries please stop by the discussion thread.
