Having made a start on the 2.10 Chester, I can't resist posting the attached chart for Copper Knight because it illustrates why I find charts easier to get an initial sense of possibilities from than tables.
CK is of course an old horse by flat standards and the chart only includes his data from when he was a 7yo, but one can see at a glance why F Chester was spot on ("The Golden Years ....", item 45) and VDW right only in his idiosyncratic sense of "ability".
Over 45 runs we can see how CK peaked as a 7yo and has since been the subject of age-related regression. That of course does not mean he can't still win races - three so far since he peaked. But it does in my view help one judge what is now realistic and what isn't. And of course it highlights performances which need to be looked at carefully to reach a judgement as to whether the slope of the green line from 14/07/23 is a fair reflection or maybe suggests his current ability is rather lower. (The races on 21/07/23, 23/08/23, 09/05/24 and 25/05/24 being in my view, the keys to that judgement.)
For the avoidance of doubt, CK is the only runner I have looked at so far, so I am some way from reaching any conclusions on the race.
