"X-mas Stout"

I just kegged what I'm calling X-mas Stout. Final gravity was 1.003 (damn near water). My triple gauge hygrometer calls that ~5%, but a few online calculators call it 2.8% (??). Mr. Beer says the unmodified kit will be 3.7, and mine should be a bit higher, so I'm tending to believe the hygrometer. I'll do some research tomorrow to figure it out. When the keg is ready, I'll do some research the old fashioned way as well.
