Why'd you bump it down from 6 brake points to 4?
It's in the readme dude:
Version 1.1 update; decreased number of service brake points from 6 to 4, to give B1 brake rate of 0.75 mph/s.
The M7 manual states that the minimum brake rate is 0.75 mph/s, so if the full service rate is 3.0 mph/s then naturally, setting the number of brake points at 4 gives the correct operating characteristics for the minimum application.
