    [QUOTE=mebaran;12892731

    I say a team has a 56% chance to win an event. This is based on a framework I have deemed statistically significant. Step 1 complete.

    [/QUOTE]

    This is the only problem. How do you come up with 56%? Its just a guess.

    From an alternative perspective though I can see how theoretically it could possibly work long run but you would have to make sure you stay consistent with your formula. Any variation on your estimates could be disastrous using Kelly.

    !!! This is exactly why many proponents of Kelly recommend using fractional Kelly so that any errors in calculation don't cost you growth.

    The variables in the Kelly equations are well proven and not just in sports betting. The only sensible criticism of Kelly is what was discussed earlier, the inability to accurately determine edge per wager.

    The closing line is the markets' prediction.

    What if you had already placed the first wager at 2.5% of bankroll?

    if using Kelly.and i believe I have a 55% probability of winning bet..that would be 5.5 % of my bankroll.
    Now my question is ...if i want to use half kelly...do i simply divide 5.5 % by two? ..2.75%

    For simplicity's sake, yes. (Kelly calculator says 2.7553%)
