The correct dose of Prascend is the one that controls ACTH and that is not dictated by the size of your horse.  As your mare's ACTH is so high and she has been PPID positive for at least 2 years I would expect she will need over 1mg to bring her ACTH down prior to the seasonal rise.  You can read more about treatment of PPID here:
