For a simple person seeing as Excel is not my strong point.
I know how to formulate a backing spreadsheet, but looking for a laying formula.
H = Stake I = Odds J = Bookie K = W/L L = P/L
What I want to know is what should be in "L"
For example, I lay something @ 1.34 for £10. My liability is £3.40 Obviously if the lay is successfull, I win £10 minus commission. If the selection wins, I lose £3.40
And is it possible to include the deduction of commission at 5%?
