The draw bias, if there is one, can be very hard to call on the July course and watching those early races is the only way to find out if the draw is favouring either side.
In my experience, the middle of the (undivided) course seems the best place to be if there is any give in the ground. This equates to high numbers when the far side course is used and low numbers when the near side course is used. So, today it should be high numbers favoured, but I’ll wait and see.
