Pulse width down-duty cyle up?

[VHR]

How can base pulse width go down, but duty cycle go up with increased rpm?

DC[%] = IPW[ms] * rpm / 1200

If rpm increases much more than IPW decreases, then the DC goes up...

for example:
- say IPW is 10 ms @ 1200 rpm: DC = 10 * 1200 / 1200 = 10%
- say IPW is 5 ms @ 4800 rpm: DC = 5 * 4800 / 1200 = 20%

Thanks for the reply Joe. I knew it would be you with the answer. I can only speak for myself when I say you are a tremendous resource here and once again, thank you.
