Not trying to be an antagonist here, but there are three other guys that cook with me at times. If this rule was not in place we could cook as two or three teams in a contest.
There is a husband/wife who does something similar in IBCA. You are never quite sure which pit the meat came off. Funny thing is that IBCA pits (intended) all entries against each other. Wife's entry 6th, husband's 7th. Damn near every time.
Edited to add, I am slow...
