Yeah it's mostly about the electrochemistry of the battery. High regen puts juice back into the battery at a higher rate than is optimal; it's analogous to high acceleration, when lots of power is drawn and efficiency is not as good as when you press that pedal more gently. That said, I prefer high regen for its superior control via the pedal. Either way (low or high regen) you have to pay some attention and adjust your driving style to get the most out of your electrons -- if that's your objective. Mine is usually to get from A to B not with the greatest efficiency but with the most fun.
High regeneration vs Low
Seems to me that when highway driving (NOT city driving) it shouldn't make much difference which mode you're in. My (admittedly weak) grasp of physics tells me that if a certain mass has to be brought to a stop in a certain place, high regeneration will require power until close to the stopping point, then lots of regeneration will occur over a short time when the right foot lifts.
With low regeneration you take your foot of the "gas" earlier, so you have low regeneration but for a longer time. My guess is the result should be the same amount of juice fed back to the battery.
This argument assumes no use of the brakes, of course, until the stop is made. And it would not apply in stop and go traffic where you can't take time to anticipate a stop.
Anyone with a better scientific background care to comment?
