Very first day, 100% SOC, 88 mile range on the gauge when I picked it up at the dealer. ~55F, raining. We drove 78.5 miles, something like 70-75 of it on highway, in the rain at 65mph. We arrived home in turtle mode, stopped 3 feet short of parking in the driveway. Some of it was with the climate control on (defroster, mostly).
Normal day for 100% SOC is a stated range of 100 +/-2 miles. I drive a round trip commute on highways of about 42 miles. I arrive home with 55 miles showing on the meter, so it is -3 miles from actual. I think the last few miles on surface streets tend to increase the estimate of mileage for the next day, since it is clearly time-averaging the estimate to most recent driving.
Based on my normal commute I switched to 80% charge today, so next week I can give some estimate of performance using that. It did make me think I should edit my Nissan Leaf shirt that says "I Wake up Fully Charged" to "I Wake up 80% Charged"
I would say the stated range of 100 miles is accurate, assuming you are not on highways at 65 the whole time. The EPA range of 73 highway is also very close to correct, assuming you are on the highway, using the climate control.
