LOL... you need to stop taking it so personal supereagle -- it's not like I invented the statistics or the probabilities associated with martingale... that's just what they are. You can reap up for days on the logistics of what you're doing and yes, if you're really good (lucky), you can beat the odds but the odds are that you bust before you even double your bankroll... but the odds can be beat and that's the goal of capping. My only argument is that you (an amateur) shouldn't be selling a fatalistic system... But whatever, we'll have our little competition and we'll agree to disagree.

Dude, I promise Im not taking this personal.  Actually, I thought you were.  Is there a chance, just a chance, that the methodology for my selections could give me better odds than say a 50/50 coin flip?  Seriously.

On a 50/50 coin flip, what are the odds of 7 heads in a row from the front end?  My calculations may be wrong, but I calculate it to be 0.78% chance.  Is this wrong?

On any given pick, assuming the books are right, you have a 52% chance to lose. Put that percentage to the power of 7 and you get 1.02% -- so the odds of you losing on your first seven plays is about 1 in 100.. but the more you play, the higher the chance of busting.

Gonna lock this in because I only see the price getting worst:

White Sox [-120] $120 to win 100

Yup... you could have a selection method that produces better than 50/50 results. Do you...? That's another question.

Lets just sit back and see what happens.  If you are right then so be it.  I just have an extreme amount of confidence in my methods of making these selections that I am willing to ride this to the grave.  I really believe I can outperform the odds.  I am not naive as to think I will never lose 7 in a row, but I really believe that my pick methods along with a money management strategy will keep me moving forward.

Explain to me how, if the book has the line right, we only have a 48% chance of hitting.  Why isnt that a straight 50/50 proposition? IE: Cowboys -3 vs Giants, either it will cover or it wont.  Are the lines ever really that far off and if so does that ever really happen often enough to matter?

Kelly criterion is not flat betting because stakes are adjusted according to confidence.  Both Martingale and Kelly criterion are similar and riskier forms of money management than flat betting.

It's not 50/50 because of the vigorish.

Hey DJ, we are on the same page now.  I knew you had to win 52% to break even on money.  I was talking about whether you win or lose a pick is 50/50.
