I remember using both Acufine and Diafine to push with, and seem to recall the 800-1200 range with one, and up to about 3200 with the other...but I don't remember which was which...and I certainly wouldn't recommend the radical pushing unless someone's life or livelihood absolutely depended on it..;-)
