Why do you need an average(cheat)sheet to judge BBQ? Does it not make more sense to start at 17 when we sit down at the table and wait until we open the box to start judging? It' not a crime to score an awesome box of Q a 17, the world will not come to an end.
We as cookers spend a lot of money to do this as a hobby, but we all want to win every weekend! For me I just ask for an honest fair opinion of my turn in that day, not an average of years of turn in numbers. The SCBA is a great organization that I have cooked in over 100 comps and will continue to do so, we have a lot of great judges and great cook teams that I am proud to be a part of.
Just remember "IT'S JUST BBQ" it's not brain surgery!
