Hi Ianian,

From your figures the clear outcome is you can not just back every 100 or 99 point selection as they are clear losers.

You need to either dispense with some type of races, some days of betting, some type of beast or maybe the horses age or sex or some horses in particular price ranges.

For the latter I generally eliminate any horses priced <$3.30 and >=$10 in prepost markets. This improves S/R and POT% immensely.

Anyone else's thoughts?
