Notes for pedal slope:
Adjust the pedal slope is to adjust the boundaries of the low velocity and
acceleration zone. The pedal slope is, a small the low-speed region will be smaller
and then you will fell the acceleration is much smoother when stepping on the
pedal. Other wise, low-speed zone is bigger and comparatively you’ll feel the
acceleration is steeper.
If you need to thread one needle by foot-tread( like supplemental needle), you
can set a bigger value to pedal slope and then it is much easier to make one
needle.
