- minimum braking, carry no extra speed into stops. This means some long glides, one is a mile long before the stop.

My Scangauge-reported average speed? 30 mph, about 5 mph higher than my normal. I also lost about 10 mpg. I'll gladly trade 2 minutes for that.
This is a good explanation of much of my driving too. I go faster than you but I have largely emulated your driving tactics and strategies and I own nearly the same car, though I have modified mine quite a lot, as you know. My UG won't give me ave mph because the EOC routine messes up the data (I get numbers like 87 ave mph sometimes). Much of the difference between our 90 day averages (88 mpg and 61 mpg) might be explained by speeds? My goals are to hit, exceed, or stay within 5 mph of the posted speed limits, which are generally 50 on the main roads, 25/35/45 on the neighborhood streets, and of course 65 on the freeway. I like to imagine that what I am doing can be scaled-up to the MT parts of the US auto fleet without radical changes to roads or speed limits.

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.
