If you watch Jeff's videos or dvd you will see he really leans on the grader. There is a whole lot of stone there, so when the stone gets to where you want it to be STOP.
I personally would do all the rough cutting at once and then reface the stone and then do the final cutting. I think this way you will save alot of wear on the stone and you will get more uniform cuts
