I'm with you BC the only way to work out form is to see what the horses has done in the last couple of races and what class it did it in then you look at the class of todays race....you also have to consider weight and a few other things....sorry to the time ratings people...i don't use them....but then most of my races are 1600 up in my view it is the best type of race because your horse can have a bad start or get blocked in or what ever but if good enought can still win
