Your better way to gauge load will be with a vacuum gauge rather than throttle... use the search function of this site in the upper left hand corner and search for how to use a vacuum gauge for driving with load and P&G. There was a thread recently.

Then on a glide I could flick the switch to effectively stop any fuel from being injected but keep all electronics going, then turn the injectors back on again for the next pulse.
This had been done. I have one too. Search for injector kill switch installs for your model here on ecomodder...

Closer to 55 mph is better for cruise, as long as it is safe, You might pulse to 65 and glide to 55. That's what I do, seeking to average 60mph (a mile a minute).

Good luck... you'll get it... I did (mostly).

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
