I'm not sure how much KW weighs, but an estimate of how many drinks it would take to get a BAC above .15 is a conservative 8 or 9 drinks. That's alot. That's not a whoops, I had one too many beers number but a I'm a binge drinker who has little regard for myself, my family, and the community number. And remember, this aint his first rodeo- it's how he rolls.
I have been told by alchohol experts that ONE beer or oz of booze in a cocktail is enough to bring blood alcohol content up to near .07 (just under the legal limit btw) so I would suggest that for a test of .15, it might be closer to 4 drinks in less than an hour would put you around that mark. 9 drinks would have most people blitzed and I am sure above .15 depending of course on how long the time of consumption is. A man will process approx. one drink per hour without getting much drunker than perhaps a couple drinks worth (usually two drinks is going to put an average person over the legal limit).
What? Alcohol experts? No. You heard of Google bruh? I might believe that if you were drinking straight Everclear, but otherwise nah.
I'll cite my sources - it might even be relevant to how the university looks at the situation.
I'm in a fraternity at UNL. I'll be a senior this coming year, so I've seen the university go through several deaths, sexual assaults, and changes in their policy on alcohol consumption. Since the death of a fraternity member two years ago, every fraternity member currently in a chapter has gone through alcohol education classes. Every new member who joins goes through this same class, and I've been to a those the past two years as well. They bring in officials ("experts") from the university to teach us safe consumption, etc etc. The "experts" at the University of Nebraska-Lincoln teach that a standard drink, for the average male, will raise a BC by about .015.
I realize different experts will say different things. But this is what employees of UNL teach.
