That's just the standard copy and paste thing they send to everyone. But your teslafi graph from a page back is pretty alarming - that was a week or so ago, is it still trending down? That's a crazy low number, and should have triggered something at tesla. My car is twice as old as yours, and while it dipped pretty low recently, it's nowhere that low.
I'd advise getting proactive about this. Do a mountainpass style reset of the battery. Do at least one more complete depletion-recharge cycle - run it down as low as you dare (1%), charge to 100%. And then use the charging cycle technique I posted about a page back - these things got my battery back to a normal number over the course of several weeks. If doing these things now (not in the past - lets move on to now) don't get your numbers back up to normal, then it's new battery time.
Edit: you haven't mentioned driving style, but have mentioned that your wife also drives it. Do either of you have especially heavy feet? If so, you might try cooling it for a bit, see if that helps. It's not really supposed to make a big difference, but it does seem to in my case, at least a little.
