Scott, I was myself judge for the IPMS-Belgium contests. When I was in doubt for an element, I always tried to inform myself and, in last resort, doubt was a benefit for the modeller.
But I remember some big errors made by auto-proclamed specialists: one of them said me that an Albatros D.III under Udet's colors was the best representation he ever saw...
...That was an Oeffag...
After that, and other constatations, I decided to never judge again.
