Well done Leo and JD getting a winning start to October. If I've left anyone out, I apologise; please leave a message on this thread and I'll update.
It seems the ground was very important to Ace Impact, and, in a negative way, a few of the losers. I saw a very experienced punter and good judge (Terry Norman) on twitter saying ‘this is why the ground is the most important thing in racing’. I’m far from convinced this is true, though have no data to back that up.
I think most horses will react unusually – positive or negative – to extremes of ground, but in the range of good to firm to soft, I suspect most horses run to within four or five pounds of their median rating (all else being equal). Perhaps we notice much more the big names who reportedly need a certain surface (Trueshan anyone?) and extrapolate that way too much. There will be a way of getting data on this but I wondered what your thoughts were before I set about doing that?
