Well done, Kirk.
That 2.2 lbs. the last week would be an awesome average. It might settle down a little lower, but if it stayed, that'd be sweet.
I usually lose around 1.6 lbs a week (or did in the past, I haven't tracked any numbers this time at all), and it's always steady. I'm getting more active so I try to eat a bit more to match it. I don't usually eat odd stuff at all, and don't binge except maybe at Family Day where I eat tiny bits all day until I finally can't eat another bite, but that never amounts to moving the scale one way or another.
