Thanks for plugging the parameters into your program, I expected
that the parameters such as inductance, frequency, etc. would be easily
predicted by the program. When i mentioned that I didn't think most
computer programs could predict the performance, I was refering only
to free air spark lengths with occasional strikes to various objects.
I've dismantled the coil at the moment to do some tube coil work,
unfortunately I don't have the room to keep multiple projects set up
and working simultaneously (also, i tend to borrow parts from one
coil for another). I'll put the controlled spark length tests on my
to-do list.

I used a lab type wattmeter, and adjusted my variac setting to obtain
equal wattage inputs for both coils. The inferior coil does seem to draw the
640 watts at a lower variac setting, even after adjusting ballasting and
sync gap phase for best performance, probably due to the lower surge
impedance as you suggested.

I agree that comparisons are important and I'm always hopeful that more
coilers will begin to make more comparisons.
