I'm betting 80% efficiency would be a reasonable guess... We used that number a lot for thermo-mechanical systems... ;-)
This begs the question of why have regeneration on when coasting? I can see it for braking as the kinetic energy otherwise gets wasted has heat, but when coasting with regen on there are losses as you point out due to conversion back to electric charge. Why not just coast (without regen and thus slowing less), and then if braking is necessary regen with the brakes (which as I understand it is what happens when regen is set to off)?

From what I read, the coasting function turns off regenerative braking.
