I'm new owner to Honda Clarity. Charged car overnight with include cable at 110V and this am the car said I had a range of 100. Does that make sense? I though max was 89
I see the Honda Clarity Electric (the BEV version of the car) is rated at 89 miles by the EPA, so I'm guessing that's what you have? That's not the maximum range, that's just the average range the car gets when driven according to the EPA's test procedures, and it includes a variety of driving situations, such as slower driving in the city and faster driving on the highway.
As you gain experience, you'll probably come to agree that the car's range estimator should be called a "Guess-O-Meter" (or "GOM"), as
JyChevyVolt suggested. GOM is snarky term which I think originated among Leaf owners, because in the early years its range estimator was notoriously unreliable. Your actual range will depend on a lot of things, including your driving habits (lead-footed or cautious? Jack-rabbit starts and slamming on the brakes at stop lights, or gradual starts and stops, coasting where possible?) as well as how much you drive in stop-and-go traffic vs. highway travel. It will also depend on whether you use the cabin heater or air conditioner, and if you live in a region where it gets very cold in the winter -- let's say, 20° F or below -- then you'll find the car's range is less on a cold day.
But the speed at which you drive has the biggest impact on range. If you want to extend the car's range, then drive slower when you're on the highway.
And welcome to the world of BEVs!
