I would imagine that, in practice, EoC probably provides a little more gain than can be predicted by these charts, depending on how they're made.

That said, I don't EoC in my Insight as I figure the savings, in absolute terms, are probably peanuts compared with driving at 80% load in lean burn.
I'm not entirely sure what is taken into account. I'd imagine the alternator is on the engine, but I'd highly doubt if they have anything else attached.
