WM Megalite/Summerlite Weight Over Spec?

Took the plunge this weekend and got a Megalite Long for myself and a Summerlite Reg for my wife (http://www.bentgate.com/ 20% off everything until 12/1). Very nice bags but they both came in almost 2oz over the spec on WM's site.

Megalite 6'6": Measured=26.8oz, Spec=25oz
Summerlite 6'0": Measured=20.5oz, Spec=19oz

Just wondering if other Megalite/Summerlite owners have notice bags being over spec or if I inadvertently got bags with 2oz down overfill. Not really a big deal, just curious. I'm guessing the former over the later but certainly wouldn't complain about extra down ;)
