What’s you’re highest ev range it’s reported? I’ve hit 60 a couple times with this being my highest. But most days it starts in the low 50s

Ours hovers around 60, but we've hit 66 a couple of times. That's what the computer says anyway. Knowing how wildly incorrect the HV range is, the actual EV range may be a wee bit off, so to speak.
 
My high water mark was 67.2 m
One person, moderate acceleration, level ground, no non motive drain on battery, max speed 55 mph, 75/25 city/hwy, temps in 70s
Now w A/C and temps in 90s I’m seeing 62 to 64

Upper 60s/low 70s. I've noticed running the AC more and the higher temps have had a slight impact recently.
 
82km (51 miles) is the highest I've seen so far when first getting into the car in the morning after a full charge. But, by using the regen paddle to slow down on my city driving trips, I've had the sum of actual distance driven + range remaining hit 88 km. (55 miles).
 
Sorry, but downhill regen EV Range doesn’t count for bragging rights until you reverse the route and go the same distance uphill. I could go down Pike’s Peak and beat that number but it wouldn’t mean anything.
 
I must be doing something wrong since I was so happy when we hit our high, 57!

I guess the question I have is, are these high #s real? How many are checking their actual mileage with the EV estimate? I’m probably remiss in confirming my actual #s with the projected.

That 84.5 miles is pretty amazing, but I'm really interested in the HV of 306, which looks pretty accurate.

I'm curious if you do quite a bit of driving in HV mode, so that, unlike those of us who have been driving almost exclusively in EV, your car has had a good chance to actually measure gas usage rates over time, and whether or not you already have the HV Range Fix installed.

I've found the EV range to be very accurate, so long as my drive is similar to the previous drive from which the car is calculating the range. Changing driving conditions/style will throw the range estimate off, as the car can't exactly predict how you're going to drive. I do think that Honda uses too short of a time interval for calculating this estimated range--it seems like it only bases the calculation on a very short distance, perhaps less than the last 100 ones or even just the range from last charge. This contributes to inaccuracies in the range as even a single drive that is different than usual conditions can cause the estimate for the next drive to be off. Using a longer range/time period would average out the inconsistencies and provide a more accurate estimate in the long run, I believe.

I found that after I disconnected the negative terminal of the 12V battery (to clear the triple error issue) that my HV range became accurate. Not that this should be a necessary step to get an accurate range reading.

I suspect that is just a temporary workaround to the core problem, and after the next gas fillup, the problem would return. Hopefully, the HV Range Fix from Honda will provide a solution to the problem that all of us who charge our cars up regularly, and use little ICE have suffered.
 
Since my driving conditions for the first 4 months has been very similar, I too have found the EV range estimate to be rather accurate. I don’t let it go all the way to 0, but when I use the odometer milage to check the reduction in the HV range estimate, it’s always within 2 miles of each other. It seems the shorter the milage before charging the larger the discrepancy. I wonder if I let it go to 0 and ICE start if it would match even closer?
And even if it didn’t, 2 miles is only a 3-4% error depending on the range I’m getting. That’s a pretty good algorithm considering all the variables involved.
 
I've had my highest EV predictions this month. A couple at 60 and one at 62, but I have had less accuracy on these high predictions than I experienced with them when in the mid to high 50's.

My real-world battery capacity has been 4 or 5 miles below the highest predictions, whereas they had been spot-on in the 50's.
