I've read it's about 70 calories a day maximum as well. I think this is for the recommended 2-4 cups of green tea per day.
Not sure how you arrive at only .12 oz. lost per year, but
70 cal X 365 days = 25550 calories. 25550/3500 calories per pound = 7.3 pounds.
So, conservatively speaking, I think the 3-5 pounds a year is pretty much reasonable.
