JUMP RACING V ROULETTE I think the Roulette comparison was just to show bookies have a greater edge starting on jumps than roulette.
I agree though the edge can be greatly shortened by taking a whole host of things into account.
The other thing you cant do with a roulette spin is use the negative as an advantage as said above
Weed out the bad jumpers as they are most likely to fall and you shorten the edge.
Roulette has no form (other than laws of probability ) so each slot has exact same chance on any one spin
its diff with horses however but remember horses are priced accordingly if horses were priced as roulette
numbers a 20 runner race all horses would be about 18/1.(bookies dont play without an edge)
Some of those courses with high fall numbers there has to be reasons.
some are obvious so not so
