The losses from hard acceleration are a result of electrical resistance, primarily internal resistance in the battery but also some in the wiring and motor windings. Doubling current doubles motor power, but quadruples resistance losses. Lots of time at high current heats up the battery, which is not good for it.
For a highway trip where you are getting up to speed only once it won't make a significant difference, so there is no need to get in the way in the merge zone. Around town, the difference between moderate acceleration and mashing the pedal every time the light turns green may be more noticeable. There's still no need to get in the way though, as half of maximum current results in a quarter of the maximum resistance loss. Just accelerate with the traffic, don't speed, and try to anticipate slowdowns to minimize braking.

September Efficiency:
2,496 miles
4.1 mi/kWh

October Efficiency:
2,411 miles
4.0 mi/kWh

November is currently a significant drop in efficiency(3.7 mi/kWh) but my husband was driving it while I was in Florida so hoping to improve the average before the month is over.

Glad to see that most are in the 4 - 4.4 range of efficiency. Based on usage and remaining charge, it puts the car's usable range close to 250 than 226/216.

Anyone on the forum have both a Bolt and a Leaf plus? I would be curious to know if they felt the Bolt has significantly better range.

It does not. Range is a matter of highway driving, and that is a very YMMV based on driving speed. The reports you are reading are mixtures of highway and city driving.

The vast majority of my driving is highway, I'd say probably close to 85% of the miles on my car are highway, possibly even more than that. Given we don't take the battery below 20% if we can avoid it we generally get about 200 usable miles on road trips(starting at 100%) and as a daily driver closer to 150 (start 80%-end 20% charge).

It would be nice if the car had a more "usable" range in that aspect but we are saving $$$$ so who am I to complain?😊

Better range? yes. Significantly better? No. Driving styles can easily flip the placement.

My results are dropping fast in the cold, and even more significantly with night driving. The Plus we have does not have LED headlights, and the mileage for November with a fair amount of 65MPH highway and night driving and cold weather is running around 3.7 M/KWH. Is there a way I can find out how to see "actual" energy use as opposed to traction motor use, including headlight and heater draw? (our Plus is the base model... Thanks all, BTW, for this forum!

Headlight use is not significant. Heater use and increased rolling resistance from colder temperatures are main causes of reduced range. I think the S+ (base model with 62 kWh battery) includes the larger navigation screen. If so, there is an energy use screen which displays graphs for traction motor, climate control, and auxiliary (12 volt) power use.

The dash efficiency includes auxiliary power draw, no?

I gotta think that dash efficiency graphic does exclude draws other than traction motor, and I can not seem to find on my screen anything like the detail that the fancier models might have- they DO have larger screens. Maybe less-affluent people are less likely to be energy geeks? seems like the opposite would be true....
