Regen in Raven MX with 2020.8.1.1 observation.

On a cool day (72°F) full regen is not available until 80% or lower SOC. The yellow warning band does not appear, it just will not move the power needle all the way up to 60kW+. This is lowest threshold I've ever seen in an EV. Many are 90% or higher. This indicates a smaller top buffer than is customary.
Even at 50% SOC, it will derate the regen at temps 58°F or lower by displaying the yellow dotted nerf line.
It seems to lack a Departure Preheat function to assist this.
I've never observed a regen higher than 70kW which is very low for a 5000lb+ car with dual motors.
Pulsing can often be felt during one pedal driving at low speeds which I believe to be motor poles.

I assume this normal. Not saying it's good or bad, just an observation.
 
Another data point. By leaving the car plugged in and charging to 80%, at 54°F there was no nerfing of regen.
So it's probably the battery temp sensor tables that are affecting the regen disproportionately.
I'll leave it plugged in every night now.
