She's picking up speed! It looks like she's averaging 4 ounces per day. (Previously, she was averaging around 3.4 ounces per day.)

Crazy estimate for 6 months: (80 days from now)
41.5 lbs @ 3.4 oz/day
44.5 lbs @ 4 oz/day

Ultra-crazy estimate for 1 year: (263 days from now)
80.3 lbs @ 3.4 oz/day
90.2 lbs @ 4 oz/day

Obviously, she'll have to slow down before 1 year. :-)
