In all cases, the ramp shape number is the PWM output at half throttle, as a
percentage of its full range. So, for example, in Figure A-3, a 50% ramp shape
gives 35% PWM output at half throttle (halfway between 10% and 60%). A 30%
ramp shape gives 25% PWM at half throttle (30% of the range {which is 50%,
from 10% to 60%}, starting at 10% output, or {[.30 x 50%] + 10%} = 25%).
