I use a similar technique, except I follow engine load instead of TPS. For my '95 Tercel on a recent highway trip, I found that at highway speeds, ~ 40% corresponded to 60 mpg, 50% to 50 mpg, and 60% to 40 mpg between about 55 and 65 mph. I'm still tweaking it to find the best balance between speed, load, and mpg. Too little load and the car loses speed; too much load and the car loses mpg.
