I think the problem with competitions is that most folks are looking to get descriptive feedback on their beer from people they expect to be qualified in analyzing beer. The problem is that this is not the purpose of ANY
c-o-m-p-e-t-i-t-i-o-n; it's a competition. At the end of the day, someone wins and everyone else loses; that's the spirit of competition. I understand that the
idea of BJCP sanctioned competitions are also to provide feedback to the contestants, but that is just a "casualty" of the process, it's not the point. At the end of the day
the point is to determine which beers win the competition. This is where the fault lies in trying to use a competition for any kind of useful feedback; it's a crap shoot, and sometimes your beer is being analyzed by Who_Knows_Who because they needed more mouths. Sometimes the feedback is helpful and sometimes it's crap, and you're left to decide which it is. Then again, sometimes you just want to battle and win that trophy!
I think most folks entering a "competition" are actually more interested in having their beer analyzed by someone who is very qualified to do so and garner descriptive feedback from them about any/all aspects of the beer than they are to get some kind of point breakdown of their beer and win. The problem is that there is no such venue for this type of task (business idea here!). It's either a "competition", or it's your friends/LHBS to get feedback. If there was a service/store/location where I could take my beer to have analyzed by ____insert__famous__beer__guru__here____ and get their feedback on paper in paragraph form without any point breakdown, you can be sure that I'd use that service. It doesn't even have to be a famous beer guru, it just needs to be a service that utilizes highly trained persons. Once the spirit of competition is omitted, the analysis of beer becomes easier to perform from an objective standpoint.
At least, that's my not_so_humble opinion.
