Beer ration correction

My nameless friend, whom we shall call Alena, tells me that her husband has corrected her information on the number of beers you can drink per day and still remain under the ration limit. Her husband, who is an otherwise perfectly charming man, is a stickler for accuracy by virtue of his profession. According to his no-doubt flawless math, you can in fact have 6.1 beers per day. So rest easy, beer lovers, and stay out of my way in the wine aisle!
