How I confused my "Consumption" display today

By visiting Eldorado Canyon, that's how!

The descent into the canyon is about 12 miles, and takes about 10 minutes, owing to speed limits.

No throttle necessary, and switching between B and D to maintain the limits. Instantaneous display at 99.9 the whole way down, full battery bars at the bottom.

However! The bar graph display of 5-minute increments showed all black. 1 bar showed 75 Wh, the 2nd showed 50. But they were solid black, not full-scale as one would expect. I think it just fell out of the parameters the computer would expect, so it got confused.
