I think I'm wasting my time, but on my daily commute I have a long, downhill section that typically is fairly quiet, so I get a really prolonged shot of reclaimed energy (~70mph to ~5mph) back into the battery, and constantly hope to see the range go up by a mile. It never does, even if it just dropped, so I guess it never does, no matter what? I get that you don't want it flitting up and down all the time, but just every now and then would make me feel better
