Driving in L uses More Energy?

My 2020 Bolt seems less Energy efficient. :eek:

Despite my careful driving (I'm a former Driving Instructor), and a Technique of +53.5 (up from 34.5 when I first got the car), my average mpkW went DOWN from 4.9 (high was 6) to 4.3. And, not once, did I see the green bar indicating excess energy.

However, on the way back to my place from the store, I stayed in D, and used the Regen Braking Paddle (friction brakes to stay stop, or stop because I misjudged the distance), not only did my mpkW increase to 4.6, the green excess energy bar appeared.

Has anyone else noticed this?

Short answer, no, I have not experienced this.

Longer answer:
I can't really comment on why you didn't get regen while "going to the store" and driving in L. Regen depends on how you modulate the accelerator and the terrain. Also, your miles per kWh depend on a lot of things. Regen is one but there are many more. So there's no real way to answer your question of why your efficiency went down to 4.3.
Pulling the paddle is the most aggressive way to generate regeneration, but overall my guess is that you get the same amount of regen if you use L or the paddle. It's just that the paddle provides a lot of regen, quickly, but driving in L smooths things out.

Your battery was fully charged and hence it would not activate regenerative breaking

To avoid this problem, I set my maximum charge at home to 93%

I always drive in L (sometimes use the paddle as well) and the extra regeneration gives me more capacity/miles per charge.
