To me, at this time you are a relatively new and anonymous poster, so, why don't you give your background? You seem awful sure of yourself. How do you know you were right and they were wrong? Are we witnessing the coming of the next Gordon Strong?
Putting the snarkiness aside, judging can be subjective. BJCP judges across the board do a great job of trying to get it right and they usually do. A head (lead) judge's job is not to disregard or change the other's perception of the beer but to come to a consensus with the other, often less experienced judge. There are few judges out there that can get all of the nuances to every style. I am a national BJCP judge and I have been paired with judges that have no credentials that were amazingly good and on rare occasions some that thought they knew it all, but didn't. Most judges are aware of the shortcomings of their palates and work very hard to get it right. In spite of inherent limitations of their senses they usually get the best 3 to the medals.
Remember, homebrewing and judging is a hobby. There is no money awarded. 99% of the time it is for bragging rights and feedback. When I get back 2 different interpretations of a beer that I entered, I read them both and try to see what the difference was and compare them to my notes. I usually learn something.
Other that getting a mass spectrometer for your homebrew club, I think the system works well within its obvious limitations.
