Well this has been entertaining ...
As I understand it, on level 7 you are betting $943.43 to win $10. Best of luck on that 7th game, should it come.
I don't understand your math though. For the illustrated betting seasons, it appear there were 62 wins and 77 losses for the opposite game. You would have had better results over those samples just going with the martingale.
For the 2007 Patriots, there were 10 martingale wins and 1 loss [the series wasn't closed out]. Just using your martingale, you should have netted 9 units [if I understand the progression]. Using $100 units, it would be $900 [I understand that is what you were using, but I might be confused]. The opposite series was 4-10 that year, or -6 units. I would think you netted 3 units combined, yet the caption is
Win $1,059 – ROI 25.9%
Equal weighted bets would have gone 10 - 4
Equal weights on the power team over 10 years went 77 - 62 or 55.4% ....
Anyway I liked the concept of yours. I have used opposite systems on craps, but always cancelled opposing bets. But that was just so I didn't look any more stupid than I already did
