There be a lot more variables than 'times' in trots as you know Kev. Barrier positions, different tracks, race tempo, where they are in the run.... heaps more.

Eg...

Horse can go 29, 29, 29, 29 = 1.56
But can't go 30, 30, 28, 28 = 1.56

29 as quick as they can go.

When race is run per 1 they'll be competitive. When run per 2 they won't.... be beaten bout 20m+ in fact. Same time but competitive in one and not the other? So comparing times like that a fruitless exercise?
