Default Brake pedal ratios

I'm working on my pedal assembly and figured some folks might have an interest in this information at some point. It's frustratingly difficult to find definitive values on brake pedal ratios for these C3s.

Measurements taken from an 82 using a tape measure and my calibrated eyeballs.

Manual brake pedal ratio = 5.79
Power brake pedal ratio = 3.44

Measurements
Pivot to manual pin = 2.375"
Pivot to power pin = 4"
Pivot to center of pad = 13.75"

The end of the tape measure was at the center of the pivot when these pictures were taken even if it doesn't appear so.
