Is there a reference or written set of guidelines for tournament heralding? Often times at events I will receive multiple sets of instructions on how to oversee matches such as, "Only call clean or unclean at the end of the fight if the outcome is changed by that of the cheater" or "Actively call ignored shots". In my eyes there should be two sets of guidelines, one for one on one fights (Single Blue, S&B, Champions) and one for group fights (Alpha Omega, 4-Man, 10-man, etc.). The one on one fights tend to be less chaotic so its easier to use the Clean/Unclean format but when you start adding more people the level of chaos increases exponentially and a Call As You See format should be applied.
Personally though, I do not like the clean/unclean format to begin with because it doesn't provide either of the fighters with information about what went wrong.
