Limited example size of only 1 car, your mileage may vary.

My input was only as to how much does P&G gain over just driving the average speed and is it worth the effort.

It can be significant if you done correctly, not if you don't.

Serious P&G do it regardless of grade, doing only when the gravity is in you favor edges the advantage towards your style working.

I use DFCO when gravities helping which isn't often here, other wise just N coasting to stops and driving without brakes.
