You reference nothing to get to your losses. I would expect that we are recovering more than half. Still, even recovering half is much, much better than recovering ZERO.

The hybrid still has rotors and/or drums. The amount of regenerative recapture is dependent on how much isn't expended as friction/heat in the conventional part of the braking system.

Rather than try to assert a negative, why don't you produce statistics show just how much you actually recover? Anything you do manage to put back into the battery will still experience losses again on the way out of the battery, down the drive train and down to the wheels. Is it really a paying proposition?

Tests show that up to 70% of the energy is recovered using ONLY FWD regenerative braking

Yes!!!!!!!!!!!

These are cars but show that regenerative braking results in TOTAL energy savings of about 30%.
