I agree that that's pretty good, although it still leaves you vulnerable to a page that goes viral enough to get triple the number of allowed views. That will block your 3-month rolling average for 3 months, but if your monthly traffic looks like this:

    Month 1:  50k views
    Month 2:  50k views
    Month 3: 400k views - no big deal, sometimes surges happen
    Month 4:  50k views - you know, you're starting to push your limits...
    Month 5:  50k views - OK, at this point, we need you to upgrade

At that point, the demand to upgrade looks pretty strange.
