Partypooper.....very simply the amount of horses running around over here is a lot less than eastern states...it is a bit like Hong Kong....they have limited numbers of horses running around and the fiorm is a lot easierr to read(unless there is some shifty stuff goping on) so you can work out your ratings a lot easier.
A lot of brisy horse come down to sydney and melbourne is where the money is so a lot go there as well....so you have a huge mix of horses all over the place.
