somewhere recently there was a discussion about the power meter still reading a small positive number once stopped.
The worry was that the battery was still discharging.
Well I had the opposite experience today. Using OPD I cruised to a stop at traffic lights and the power meter was still reading -3 for a few minutes, it then changed to 0.
So maybe there's just a delay in that circuit,
I don't see how there could be -ve power with the vehicle stopped.

When I see +ve number, I won't worry that the battery is discharging.
 
It feels like it's just the display doesn't bother to update when stopped sometimes, so you just see the correct value from just before you stopped.

Applying the EPB always sends it to 0, and pressing the brake often does too.

There is a slight possibility that if you don't see the auto hold or epb come on and you're on an incline, then a positive value might mean it's sitting there just using energy to stay still with the motor ?.
 
Personally noticed both trends.
I have noticed in One Pedal Driving, that the car can Roll Back... up hill.
So I personally believe it's throwing a bit of reverse into the mix to bring the car to a stop (would save brake wear).

Since it's a faff to put it into One Pedal Driving I rarely use it (should let us save modes...)
But I have noticed I have to push the brake down when stopped for the AutoHold to take over and then the power reading shows 0%.
If i just hold it gently on the brakes it will continue to push a little (3-5%), which would be to allow the car to creep.
