We know regen is not 100% efficient but it would be nice to pin down the real number.
My thoughts as well. I would suggest running up to 60 mph then slowing down under three conditions:
1) In D only allowing the car to slow down to less than 10 mph, maybe even 5 mph before braking.
2) In ECO to the same stop or speed.
3) In ECO, but braking steadily at about twice the force of ECO regen down to the same stop or speed.
Then let's integrate those graphs.
