Look at how close your track is to your middle fingerhole. I'm not sure what the exact numbers are for classifying you as a low, medium or high-tracker, but the closer the track is to your fingerholes, the higher your track.
I believe around 1 1/2" is considered normal. Less than that, you have a high track, more than that, you track on the low side.
