I have been using a selection method that has only 5 rules. So far, I have had 105 winners from 550 selections with a strike rate of 22%. My question is what staking plan would improve my profit.

Outlay $550
Return $565

Average div $5.67

You sure know how to pick the right time for that type of question.

Stressing that I am not necessarily recommending this particularly for those with weak tickers, I'll run the Kelly Criterion by your claims.

Edge = 2.7%
Odds = 4.67

Edge/Odds = 0.58%

Suggesting you stake ~1/2% of your Bank.

Staking 1 half of 1% probably won't get you into too much hot water.

I prefer percentage of bank, but i have been trialing the Retirement Staking Plan and i think it is pretty good.
