Because everyone is exactly the same and all beers are created equal? I don’t think you have any clue 🤣

Not completely true… I’ve blown a .078 after one beer and felt completely fine. While other times blown far less, closer to .04 or .05 but felt completely inebriated from being more dehydrated and not eaten. We’ve also tried like hell to hit exactly .08. Took 3 IPA pints to hit .082 but had previously eaten. It really depends on the person. Source: lots of friends and family as police officers who like to have fun with breathalyzers.
