Hi Lou,

I just took a look at some of my readings.  I see about 11" at 2500 rpm
and 12.5" at 3500 rpm.  From memory, I think I see around 10" around
1800 or 1900 rpm.  I get a lot of bouncing around on MP at the lower
readings though.  I think the problem is the location I'm using to
sense MP.

Bob W.
