Do we need something like this here?

[_ed_]

I think it's a good idea, but of course I would because it's something we're doing here.

Rain-affected tracks can differ so much, two tracks can both fall under the category of 'slow' or whatever but still be completely different. One can be loose and the other sticky, and there will be a lot of horses who will go in one of those but not the other.

So yeah I think it's good to have a bit more information. Although in our case it's an attempt to simplify it - what we used to do is drop a thing called a penetrometer (sounds a bit dodgy) into the track and measure how far it sinks in, and that measurement is the reading.
