LT1S Pro: reduced visibility of PWM by dropping the TOP values faster

(and reduced mid-ramp "stall" behavior)
The red channel seems to behave a little better too,
when PWM is limited to 9 kHz or so instead of 10 kHz.
It really starts spazzing out at even 10.1 kHz, 1% above its spec,
and behaves nicer at 9 kHz or below.
