Testarossa,

I understand what you're saying. Basically you try and determine the pace of the race and which horses performed well, despite not being suited by the pace.

If the time ran for the last 600m was say 34 secs and the overall time was only average, wouldn't you see from that that the first part of the race was slow, without having to do all the calculations?

Likewise if the last 600m was 36.5 secs and the time was ok, that the first part of the race was fast?
