In July-August I have being using a staking plan based on Back stakes on 4th and 5th favorites on Greyhound market. Maybe someone find something interesting for himself. Don't look at bank, because I simultaneously played on football and didn't make notes in this grid. Look on day P&L and Stakes page where you can use filter and find out the settings. July and August are good for examining, September and December are not so good.
Some additional settings: place bet 10s before the start, min back price 5 USD, max bet price 14 USD, real money bets.
Staking plan: Simple sequence
I don't use this plan due to losses. Now I'm playing on football bet. Who is Russian, he can look at the stakes out of interesting.
