tricky one this!!! Alcohol affects people differently for many reasons, so where as one person could drink 3 pints and you'd never know - another might not be able to stand after that many!
I can say however, at any shoot that I've been to where alcohol has been taken (usually a pint a lunchtime or sherry at a stick shoot) I can honestly say I haven't seen anyone shooting that appeared drunk. I know in years gone by that some archers used to drink copious amounts and even shot with a bottle between their legs... although this would certainly not be acceptable now!
I can't decide on a definite answer!
