the tooth count is 46 front and rear. The source of the discrepancy was that we didn't realize that you needed to enter the wheel dimensions for all of the six presets separately. Where the graph is showing the deviation is when we had changed the preset from the first one that did have the correct dimensions.
I guess we missed the big button that states "Current wheels to all". Once I set the correct tire sizes under all six presets I'm no longer getting the deviation between front and rear.
