how bout a staking plan of say 1 2 4 8 16 32 based on minimum price of $2 backing favs in decent races with limited (say less than 15 starters) fields, on average u should get a winner every three where as level bets would return a lot but with the staking at a $2 winner would produce 1 unit profit per winning sequence?

any more than $2 would increasy the return.. and the furthur along the staking plan the higher the profit?

winner winner chicken dinner!
