A glide lasts longer than a DFCO, but we are talking very short glides here. I would be in and out of gear or clutch down and clutch up so often that the trip would be uncomfortable and hard work. And as I won't use engine off coasting the engine is burning fuel while in neutral anyway, so we are talking maybe 15 seconds at 300 mpg against 10 seconds at 9999 mpg.
When traffic is not an issue I use conventional Pulse and Glide, albeit with the engine running while I am coasting.
You've got my intrigue

Sore leg from clutch fix. Learn to rpm matching. Only need the clutch for starting from a dead stop.

15sec /300 and 1sec 25mpg vs 10sec/999 and 1 sec/25
4 Vs 6 pulse/ mi
accelerating is the largest portion of fule consumption very evident in an all electric. Accelerating has a bigger impact than aero, this is why city suffers more than hwy.

Is that the big bump in the fuel log back in June? Looks like no trip log of pump to pump repeats. Fueling every two weeks will wash out the changes made in a weekly trip. For me it has been easyer to fule for my regular trip so that Its 200mi is an isolated test loop with a 30 mi warm-up. But thats my extra ordinary claims had to be backed up with extra ordinary testing on my truck. I would think that a steady vacuum pressure would probably yield better results IMHO.
What speed are 2200 and 2800 ?
