Range depends on a lot of things, so it'll be really hard to tell you for sure if you will be satisfied. When I taught MSF this past weekend, which is 43 miles away (39 of which was interstate), I would arrive with 15% remaining going there, and got home (after fully charging) with 8%. The next day, riding faster and with less regard for efficiency, I got home with 22% thanks to a wind shift. I could have definitely gone further if I would have tried, but my thought is why leave any range on the clock? It'll be fully charged by the time I need to ride it again, anyway.
I go balls-out on my commute - WOT from stops, 75-80 on the highway - but I usually have 40 to 50% remaining when I get home after 35 miles, 25 of which are interstate.
You will definitely be able to go 46 miles year round, but you may have to do a bit of hypermiling when it's cold, or if the ride is 80% or more at interstate speeds, or if one direction is significantly uphill, or into a big headwind.
