As a general figure , if one can have a SR of approx 25% with a mix of prices ,you are doing well, this will make a profit between 1-25% depending on the prices for that month.
It`s the short end prices that will kill us in the end if we consistantly take rotten vale to chance , that`s what the Great Done was all about.

With any system or form approach , do expect the unexpected run of outs of 20-25 before the next winner gets up , so its an idea to gear ones money management & ones head space around this reality .
It may take one month or 3 years ,but it will happen , it even happened to to Lengedary Don Scott where he made a massive loss in one year but recovered in the following year using his famous Weight Ratings ,betting to his accessed price against the bookmakers price.

E.g. Stop betting if one strikes 25 outs in a row ,then recommence once one gets up.
The median figure of outs with 25% is 15 outs , this means one should strike their winner within 15 bets 80% of the time. Maybe one could have 3 banks of 15 so one can attack aggressivly within those 15 bets.
Or make your bets really low after say 12-15 outs ,if one feels they are going to miss out on something.
Or structure ones bets to recover only half of the losses after 15 outs, until that winner gets up. Then go about recovering the other half.

Cheers.
