So, I understand the four greed dots represent the regen happening when taking you foot of the accelerator or braking. My question is how accurate is that gauge? For example if I'm going down a pretty steep hill and it is already showing four dots of regen (all the way to the left), is there capacity (or "headroom") for more regen, like if I start braking? Is there a limit of how much regen the motor can do? And how accurate is that gauge on your dash?
