I have already planed down to 3/4. The saw is a 10 inch Powermatic cabinet saw, and I checked for alignment problems when I began to sense the need for "extra" push power. All within 1 or 2 thousandths. The straight line rip was pretty good to begin with. I was ripping the other side and then went back and took out the "straight line rip" to get the desired final dimension.

The only thing I have changed recently is to have the blade sharpened.
