Not Seeing Increase in Estimated EV Range

I have had my 2018 Honda clarity for six months. I have never got the estimated Ev range over 30 miles, despite my best efforts of never speeding, using paddles, coasting whenever possible, etc. Range Usually fluctuates between 24 and 30 on full charge. I live in Northern Nevada and weather is pretty moderate. However I thought it would improve somewhat as weather warmed up but it has not. When I do in town driving only I track the battery only usage and end up getting somewhere around 50 miles on full charge but this does not bring the guess o meter estimated range up on subsequent uses. What am I not understanding on this process? And/Or should I have the batteries tested?

What kind of speed do you drive at on the highway. I know there are lots of 70mph highways and that speed will make the milage take a big hit.

Almost every freeway that I drive is 65 or less and I usually stay about 60 to 62 miles an hour intentionally.

Just anecdotally, I can reduce my range estimate pretty fast, but raising it can take quite a while. It also seems more likely to start off showing a lower number, like 38 miles, but then giving me 47 miles of all electric.

If you are tracking actual and getting ~50 like you say, I wouldn't worry much about the guess-o-meter range estimate. It isn't very useful in my opinion. I frequently get an estimate of around 40, drive for 45, then it finally goes down to 0 and I drive for 3 more miles without it turning the engine on.

Correlation between power gage & estimate range?
I'm curious, it seems to me that when I'm driving on electric (2018 Clarity Plug-in Hybrid), and I keep the Power gage approximately on the 2nd white bar (see photo) then I'm able to get about a one to one ratio between the EV miles estimated and the actual miles driven. Obviously, when I'm going up hills, or going faster I'm above that 2nd white bar and get fewer miles on my charge. Anyone else noticed that?

That’s a pretty good estimate of where you should try to keep your power gauge. In my opinion, however, it’s mostly about refraining from jack rabbit starts and trying to use the brakes as little as possible.

I was having a similar issue with my gas mileage on the car. It was fixed by resetting the 12V battery. After about a week, all the estimations were far more accurate.

2nd bar is around 60A, means you are not using too much power. From stop to start, I usually get up around 180A for a few seconds to get up to speed, and then mostly between 30A and 120A.
If you can continue to drive at 60A rate it'll probably get you close to the max EV miles, close to 60 miles during summer. The best mileage spot is 20mph to 40mph according to Honda's publication.
