Kelly Help

[FreeFall]

say I have an event:

85.71% or -600 to win

the odds I get are

-300 or 75%

according to kelly I should bet:
b=1.33 ; p=.8571 ; q=.1429 ;

((1.33)*(.8571)) - (.1429)
--------------------------------
(1.33)

= .7496 which would mean I bet 74.96% of my BR? I must be missing something. Also if you could explain why sometimes people use half kelly and if that is just dividing your resultant by two I would be grateful.

Ganchrow's Kelly calculator says that 42.8% is the optimal bet size if you're not playing several simultaneous bets.

Stating the obvious, full Kelly is insanely aggressive.

so what would you recommend i bet if I'm doing simultaneous bets? A quarter kelly for 10.5%?

No. Look for the Simultaneous Event Kelly Calculator at SBR - you can compute the optimal bet sizes for up to 15 simultaneous bets and you can play around with the multiplier. Fantastic tool for math boobs like me.

The Calculator is still accessible even though the forum is down due to Roguey's DDOS attacks
