Steve-

Looks nice, I'm just a little envious.

About that bathroom scale and accuracy.
Get it straight whether or not you'll be holding a beer when standing on it.
I've found that if you're going the 'weigh self while holding beer' route, you'll get the most consistent results if you make sure you're always holding a full beer. Otherwise you might get fluctuations as it's sometimes difficult to judge how much beer (ounces...) is left in the can when you step on the scale to weigh yourself.

Go at it with the full beer can method for a couple of weeks and get back to me. I bet you'll get more reliable results from that bathroom scale.
