Question for piano designers

[Roger Jolly]

Good question Clyde,
                                  Try faster return, not required on full 
peddling,   but it becomes critical when half peddling.
When half peddling some resistance is needed on the pedal,  to feel the 
just about to lift point.

Regards Roger
