for speeds up to 0.07 u/ms, we decelerate, down to 30% of input for speeds up to 0.07 u/ms, we decelerate, down to 30% of input

hence 1 = a * 0.07 + 0.3 hence 1 = a * 0.07 + 0.3
0.3 = a * 0.00 + 0.3 => a := 10 0.7 = a * 0.07 => a := 10
deceleration function is thus: deceleration function is thus:
y = 10x + 0.3 y = 10x + 0.3
