That’s a pretty high SR, anything above 10% I consider good, depending on the P&L, I find a favourite system can be anything from 50% to 75%, I would say your system sounds worth monitoring and paper trading for a week or two to see how it fairs.

If I have a system at 20% I would say that is pretty good for me, I have a few systems between 10% and 25%, losing runs and profit are important too.

If you want to choose to remove the top two weights in HRB, then use the option ‘Pos in Weights (exc cl)’ you’ll find it in the Horse Data section, select 3 to 40, this then excludes the top two weights.
