Almost makes sense.  So you estimate 50% of the potential energy went to the
regen system.  And you also estimate that about 25% of the potential energy
ended up in the battery.  So I'm concluding that your regen system is about
50% efficient.  Correct?

"/I'm not sure what you mean in your 2500' climb: first you say regen put
back
about 24% of the energy and then you say that (or something) was about 1/2
the potential energy.  Are you saying that the regen recouped about 24% of
the energy expended in that scenario?/"

I mean that the energy put into the batteries going down the hill was 24% of
the energy taken out of the batteries going up the hill, and that about half
the potential energy of the car at the top of the hill was put into the
batteries going down. The rest went to work against drag and rolling
resistance forces, drive train losses, and motor/controller losses.
