I see the best way is to increase claiming races for all ages of horses and classes.
If you set a value on your horse then if it is too cheap it gets claimed, if placed in a too higher priced claimer against better class horses you are uncompetitive.
70% of all races could be programmed as claimers with varying prices and barrier draws reflecting the price.
Accept with a $1.10 favourite and risk losing it with a claim. Handicapping becomes market driven.
It will stop the 1:54 3yr old appearing on a 5k - 8k claimer against a 2.02 3yr old.
