### How the Report Relates to the Measured Gear

It is helpful to note the relation of how the teeth are numbered and what part of each tooth is considered left and right. Tooth #1 is the gear where measurement begins based upon the start angle. Subsequent teeth are numbered according to the order that measurements are taken.

The left and right sides of each tooth is based upon the gear as viewed from the center axis of the gear. That is also true for the left and right side of a gap.
