Midpoint value should be around 1400, not 1500.

[renrut]

The "midpoint" between crawl and hot where the winch is not turning is defined as 1500, however that's too high and will cause the winch to spin when autostop is not on.

change to

#define MID_POINT 1400

and probably change the mapping logic here and test.
