I guess I'm looking forward to this the most as I engin break a lot
Its a bit different - I came from manual cars and a toe-heel driving style etc. Lift off and the regen is significant, somewhere between engine braking and hard braking ... so perhaps best described as maxing out at "modest braking".
For me, now, the trick is to lift-off at exactly the right moment to slow on Max Regen to right speed for bend/junction. This will be earlier than old-brakes-method in many cases. Either way, I very rarely use the brakes. Car is approaching 100K miles, not even got an advisory on the brake pads yet.
The other thing that is different is that Regen keeps on slowing the car ... so when i am coming to a bend and thinking "bit fast" as I come into the bend the regen is still working, so (mostly!) the speed-in-bend is still fine. Optional Bakes still available if needed
Once "enough Regen slowing" has happened I can just press the accelerator a bit to feather it - in effect selecting neutral to coast a bit, or a bit of power / bit of Regen to get my deceleration "just right"
Absolute joy to drive compared to ICE.
Also you don't have to do the "There's a straight after this bend, if it is clear I will be able to overtake" so you change down, rev up, get ready ... come round the bend and find something coming and change back up again. All that noise, commotion and driver stress ...
EV = Come around the bend, straight clear? Yup: squirt it ... much MUCH more calm. Plus I only need a handful of yards to get past anything ... even a Ferrari
Maybe that's how the miles are being calculated with a regen factor involved.
I would phrase it a bit differently:
If you just drive, and make use of Regen, then you get an overall consumption which is "Favourable" because of Regen. So it just become the normal consumption, (rather than being separately factored into consumption)
When you drive like a loon, braking heavily for corners, then you are throwing away that energy ... using Regen, instead, recovers about 70% (i.e. put-back-in-battery-and-use-it-again is about 70% efficient)
