With out "knowing" the "C" length for a clutch WITHOUT effort reduction toggle, I can assume the 7" of pedal travel from my graph was needed to straight line stroke the MC 1.25", thus the ratio would be 5.6:1. this makes the effort reduction linkage(~ratio 7:1) about an 80% reduction in force.
I would think the "C" lenght WITHOUT to be about 2"
