It's not even close to 100%, last time I read about this, I believe the recovery percentage was more like 40%-50% depending on how you calculate this number (which is really impressive to begin with).
Personally, I would prefer to feel a little 'snap' in the accelerator pedal movement, so it's easy to hold it in N, but not enough to bother you while regenerating/accelerating, and still allow single-pedal driving.
