Replying to Adjusting Forward Pressure on Axials...

Ok, this is a fairly moronic question and I feel stupid even asking it, but on the newer Axial2 heel, how do you tell when the forward pressure is set correctly? There's a yellow piece in there and 2 lines, one on each end of the forward pressure window (also looks like the yellow piece has lines as well) And I'm just not sure how these are suppsed to be aligned and whatnot, I'm used to the pivot heel, help me out.
