OK, one good beer is 3 points.
Thusly, 4 good beers are 12 points.
Now the hard question: If you suddenly realize that your tolerance isn't quite what it used to be because you've been dieting and not hardly drinking, how many points do you get back if you hurl the minute you get home from a Saturday evening of drinking and debauchery?
Four beers and I'm yokking. Boy, I sure can't hold my liquor like I used to. Probably a good thing, too.
