In my mind if I'm going for a shot I break the flipper down into 8ths. Like on acdc for me from a cradle on the right flipper, to hit the left orbit I'll flip after the ball is 7/8ths of the way down the flipper. Left ramp is 3/4ths. Bell is about 1/2. I don't think of this on the fly, just if I have the ball trapped...which I try to do every chance I get.
