I think I have finally figured out why I move so much more on a night when I am playing down and in.  It's because I hit the same spot more often, thus burning the oil out faster.  Where as the times I play a big swing, the shot permits more area, thus I am spraying the ball more, thus the oil doesn't go away as you are hitting different spots.

Avg move swinging it - 1-3 boards sometimes back to the right
Avg move straight up - 5-8 boards after 1.5 games then none because I have to swing it!

But on a side note, my scores are higher lately going straighter, but I am too slow to read the transition because I am used to playing deeper.
