Actually, I believe the ratio DOES affect the stroke. Imagine these two scenarios, exaggerated for clarity!
Pedal #1 is 12" long between pivot point and foot pad. It has a pushrod hole 6" from the pivot point....1/2-way between the pivot point and the foot pad. That would be a 2:1 ratio. If you push the pedal pad 4", the rod will stroke 2".
Pedal #2 is also 12" long between pivot point and foot pad. It has a pushrod hole 3" from pivot point. That equates to a 4:1 ratio. If we push the pedal pad the same 4", the rod will only stroke 1".
