But the handicapper has to rate a horse on what they have done, just like the thousands of others they have to rate. Taking Jeriko, he was the highest rated horse in the race last time off the joint lowest rate, yet finishes 6th of the 7 runners, beaten 13 lengths. His rating over fences still doesn't correlate to what he has achieved. Should a handicapper refuse to give a horse a rating of 145 so they don't get accused of deliberately dropping it to get in a limited handicap? Like you say, any handicap system is open to abuse. We see it year in year out on the flat with Prescott running his horses in sprints before upping to long distance when going handicapping.
Maybe there need to be changes to what races the handicapper can assess? Should 2/3/4 runner races be exempt from assessment considering most are tactical affairs and it's hard to say who has run to form and who hasn't?
