This one was mentioned in the old Turf Monthly that used to be around years ago.

Won LS (Current Campaign)

$3.50 or under.

It is profitable according to my figures. I used 40 days to define when a spell is taken and thus current campaign. You could play with this figure to work out what suits you best.



There were 72738 horse form lines in the database at this point in time. We update when we get time.There were 1039 selections for the System
There were 1019 races for the System
There were 461 Winners for the System for a strike rate of 44.37%
There were $1075.67 returned for WIN (after 5% commission) which means a Profit or loss of $36.67 or a percentage profit/loss of 3.53%

Test Another System

The Rules used were : WinPriceLay <= 3.5 and lastStart = 1 and daysLastStart < 40



Here are the reuslts with no spell.

I thought I would just mention I am using the higher of the figures on betfair for checking the $3.50, but the lower figure to work out profit.

Thank You.
