this little system is working for me.
I thought I might share it.
self devised...

1. look at races 2000m or more ( just to save time ).
2. (number of wins plus number of second placings), divided into number of starts to be 40% or more. ( after time it gets easy to calculate. - add 1's and 2's and multiply by 2.5 )
3. last start odds SP of 10.00 or less.
4. number of wins to be equal or more than number of seconds.
5. todays odds under 11.0 ( or 10/1).
6. average prizemoney of horse to 2ooo or more ( most are ).

results march 2014 bets 25, wins 11, return 46.50
april so far 2014 bets 10, wins 3 , return 16.00
