I almost never use the friction brakes. However, I find it hard to believe that there would be no difference between the efficiency of regen modes.
Maybe it's cause I don't have a complete understanding of the system but that doesn't compute for me.
After the implementation of a LOW regen mode, I grew very curious on how much additional efficiency we get with regen.
My instant reaction would be that HIGH regen would yield more efficiency as it's more powerful(?, not sure if that's the best way to put it).
But another part of me feels...
