This is a great example of why you should be a member of KCBS. Your small fee of $35.00 insures you don't have this situation.
To use five judges at some tables and six at other is NEVER fair. Even if they used a kcbs program which dropped the lowest score, you were stuck with the five scores given while others were allowed to drop a score.
Sanctioned contest by KCBS, MIM or IBCA insure a level of fair competition.
How did they determine which boxes went to which table. Did some teams have a repeat at the table with 6 judges. I would not feel I was treated fairly in this situation.
But that is only my opinion.
