On my old 486-66 it took perhaps 10 seconds to calculate, and that's only
10 points. You specify the start RPM, and the RPM step, and it calculates
for those points until it has done 10 points. It's not my favourite way to
specify this sort of thing, but in the end it solves the problems.

As for Engine Analyzers accuracy, say hello to Courtney when you get home
tonight. :-)

I'll make a run and post the output here so people can see what EA outputs.
It won't be until Friday, because I'm out of town tommorow.
