Hi there Garyf, yes I realised that you were referring to the race itself and not the individual horse. I guess my line of thinking there was that establishing some sort of a "family history tree" from each Group race would be a pretty mammoth task.

My thinking was to pick a couple or few trainers and endeavour to just back their "pattern" runners, although even that is rather time consuming with the amount of runners some of these trainers have.

And Vortech, your comments on velocity caught my attention. They probably turn out to give a similar result to what I am already doing with TVN sectional times. I might look at your aspect of metres per second when I have more time when I get back home. I'd be happy to swap any thoughts you have on this subject.
