Andy you caught me thinking faster than I type. (Which doesn't say much
since I type so slow.) I meant to agree that the Dwell Timing is constant.
Meaning the dwell angle remains constant. It's a hold over from my valve
timing days.

P.S. Engineers write better software than Computer Programmers can any day.
