TS, Rail positions can be crucial, if the rail is in any one position, and they have been racing on it for a while it's starts to chop up and favours the outside horses. Most of the time when they move the rail out, or back in, it gives the rails 'virgin ground' and often you'll see a strong leader bias on these tracks. The problem is exponentially multiplied on softening ground.

I don't know about Mav, but i record all Victorian races onto DVD, it makes races alot easier to locate, and the quality of picture is in another league to that of the website.
