the reason some of the top women are 960-975 rated has nothing to do with the fact that they physically cannot throw as far as the top men, its that they still do not have the variety of shots most 970 rated men do, or if they do have they are not as comfortable throwing them. This is beginning to change; many have sidearms now, although normally not long enough to throw off the tee, some throw rollers, etc. Val has been in the top 3 in the world for 10 years now basically by throwing short and straight and playing smarter than everyone else.
Its the women who should be taking lessons from the grandmasters haha.
