You're on to something there.

If I accelerate more slowly and use up the entire ramp lane plus a little of the slow lane before getting to 105, I can keep this down to 0.1.
Now mathematically, the two should be *very* close to equal, but they are not even remotely close in practice. Which is why I think I'm missing some obvious factor... or not so obvious maybe!

You may simply have illustrated the difference between operating the engine closer to its most efficient point on the BSFC map (slower accel), vs. higher accel. I assume your hybrid (what kind is it?) has a CVT, and it will try its best to adjust gearing during acceleration to stay close to the engine's "sweet spot", which is generally at a relatively low RPM. But when you put your foot in it and demand higher RPM/more power, it will concede, and overall fuel economy will drop.
