Just for the record: FG: 1.023
Total yield was about 4.25 gallons. Beyond the usual loss to the yeast cake and the stuff left in the bottling bucket, I managed to overfill a couple bottles, and accidentally open the bottling bucket spout and pour some more beer all over the floor.
I actually managed to crack a bottle neck while capping, so I drank it! Verdict: flat beer sucks.
