Can someone calculate backwards, what his Alcohol content in his blood was if he had 5 hours sleep and weighed 85kg?
I gave it a shot, but my calculation seems too high.
I had it up around 0.29
Weight has a negligible effect on the calculation and sleep none. You need to know what time his last drink was and then what time he did the test and what the reading was. If we guessed at midnight and 10:00am your calculation might be in the ballpark. So his blood alcohol content might not have actually peaked until 3am then it started coming back down. So maybe by 5 or 6 am he's 'sobered up' enough that's he's now just as pissed as he was when the beer stopped flowing at midnight.
The guidelines/rules for BAC calculations are;
1 standard drink = 10grams of alcohol
1 standard drink increases (on average) someone's BAC by 0.02%
The body (on average) processes 1 standard drink out per hour
If he was 0.1% BAC when tested, 5 hours earlier he was 0.2% BAC, if you go by these guidelines issued by drink wise, but there are many variables also to consider.
It doesn't really matter too much when your last drink was, it's more important when your first drink was, the rate of consumption, how much was consumed and what sort of condition your body is in to be able to process the alcohol out of your body.
