I think then you have to factor over a given distance say 20 miles as more P&G cycles of one method vs different number of P&G cycles at other accelration rates.

Yes, a slight correction is needed. What's needed is compute miles per gallon for 1 pulse and 1 glide. Assuming your pulse in linear then you'll cover 0.104 miles with 83% and 0.069 miles with 90%.
"True" FE for 83% would be (0.104 + X)/(0.005963+Y) where X is the number of miles in your glide and Y is the gallons of fuel in your glide. 90% FE would be (0.069 + X)/(0.004688+Y).
If EOC then Y=0. I ran the numbers for that. As long as your glide is >0.065 miles then 90% is better. That would most likely be true since your pulse distance is 0.069 miles, and I assume your glide distance is greater than your pulse distance. If your glide distance is 0.5 miles then the 90% gives you a 20% improvement relative to 83%
Nice test, BTW.
