Calculated personal edge is DIFFERENT for each game you bet on

For example,

Bobby's current bankroll is $10,000

Day One :

Team A +3.5 -106
Team B -3.5 - 104

Bobby thinks team A will win SU or lose by no more than 3 points to Team B 56% of the time if these two teams played under similiar circumstances "in the long run "

Therefore Bobby will wager $936.00 on this game

p*o - 1 0.56* (20.60/10.60) - 1

b= ------- = ----------------------=9.360% of his bankroll
o - 1 20.60/10.60 - 1

Let us assume Bobby belongs to the miniscule subset of the general population known as "successful sports bettors

FINAL SCORE
TEAM A 73
TEAM B 75
his $936 bet to win $883.02 was successful

Bobby's new bankroll is $10,883.02

Day Two:

Team F +5.5 -103
Team Z -5.5 -107

Bobby think's Team Z will win by 6 points or more 54 % of the time if these two plays played under similar circumstances " in the long run "

Therefore Bobby will wager $520.21 of his current bankroll to win $486.18 on this game

p*o -1 0.54* (20.70/10.70) - 1

b= -------=------------------------------------=4.780 % of his bankroll
o- 1 20.70/10.70 - 1

As you can see from the above illustration, even though both bets had similar "vigs", -106 and -107 respectively, since his preceived edge on each game was different, Bobby wagered considerably different amounts

Bobby has calculated a personal edge that is different on each game is this as good as keeping it all the same, I say yes but talking to alot of sharps they say both is good

Just wondering what you guys think ? if anybody does this for a living here.......I agree with this formula under these circumstances

PRO bettors? Around here? You ever see that EA Sports commercial with Tracy Morgan and Ben Wallace:
"Benny Wallace, wrong direction, bro."


I went through your #s. Looks like you're using the Kelly Criterion, setting your % of Bankroll Risked = Expected ROR.

I'd argue that the size of your first bet is too high. If the expected ROR is 8.83%, that should be the % of Bankroll you put at risk. My understanding is that you should not be using the "to win" amount. Ergo, I'd be laying $883 under your first scenario. I think you're putting too much risk in play if you exceed this value.

Just my two cents. Remember, "wrong direction, bro."
