Thanks for the more in-depth explanation. So, you do have access to more throttle if needed. Good.

Still, in my driving conditions, sometimes I'm bucking nasty headwind or xwind, sometimes not. Sometimes heavily loaded, sometimes not. While I have no TPS readout I'm certain my cruise throttle "settings" vary with every trip, independent of speed. Were my car to have a fixed cruise throttle position, it would cruise at different speeds. I would rather choose my cruise speed on each trip.

Additionally, guys with instrumentation tell us that more vigorous acceleration actually is more efficient than creeping up to speed, especially with m/t vehicles.

So, yeah, I do think it was a nice try but I don't see it really coming through, at least for my conditions. That you were not able to provide any before/after fe results, much less A-B-A, doesn't help.
