I know I've made jokes about the procrustean nature of the BJCP*, but in truth, that's kinda the point right?
"Here's a target - see if you can hit it" is the challenge of a BJCP contest. It doesn't matter if I've made the best shot because it was the longest or most complicated or most interesting, just how close to center I hit.
We can sure as hell disagree as to whether or not the target is correct for the particular name given to a set of parameters, but a "best beer" competition is a whole nother beast than a "best beer by style" competition
* - mostly so I can drop "procrustean". It is a favorite of mine.
