I feel that the key is to slowly roll onto the throttle and only use 40-50% load until you’re under way and over 1000
It's all about what's on the brake specific fuel consumption map. Your method might work really well. I think there's a map out there for a 1.9 liter Saturn engine. Have you seen it? I left a something out of my response in moment ago. My wheels are more aero, probably. I replaced open spoked VX 13" wheels with 15" 7 hole MINI rims, but I blanked the seven holes for a "smooth" surface. Here it is before I put the wheel skirt back on:

I thought it looked a little better than just using moon eyes.

EDIT: here it is I'll upload it for you if you haven't seen it:


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.
