Brake pedal ratios

So over the weekend I was refinishing the standard manual brake pedal to use in my TC (swapping over to the regular vacuum assist brakes from the Teves ABS). I decided I wanted to know what the differences were (besides the very obvious that they aren't they same).

I did some measuring and got 3.8 for the standard pedal and 3.7 for the TC pedal. However, I knew that I'd seen this information posted before, and I was right rbryant has this posted in the KC. However, he has 3.3 as what is listed in the FSM.

I want to know how they got that. Where are they measuring? I got 11-3/8" for the length from the pedal pivot to the foot, and 3" from the pedal pivot to the master cylinder pushrod pivot.

The TC unit, for reference I got 11-13/16" from pivot to foot and 3-3/16" from pivot to pushrod for a ratio of 3.7.

Anyone else actually measure the physical parts?
