you have to get a feel for it and do like a 1/4 turn at a time each side back and forth back and forth. if you are not careful, you'll spike one side or the other. good thing about the mme is the head room. since i got a p2 i don't break the mme out very often, but i ran the screwdriver a long time. i am actually thinking about breaking it out tomorrow for los lobos. good luck, imho the minime a/d can't be beat.
