Exactly. Honestly, I am such a conservative driver (hope my efficiency bears that out), that B regen is usually enough, but not always in city driving. I also agree that when you feather back on the accelerator carefully you can kind of feel when the friction brakes engage.
In any case, I will let you know how it goes. But given outside temps, early indications are that it does modestly improve your overall efficiency. Certainly maintaining momentum is the best, but if you have to stop...best to regen it back.
