I think the majority of inconsitantcy comes from having a different ref every game. If two people see contact occur then one may call that a foul and the other may not. Refing is all a matter of opinion and when you get someone's different opinion every night then inconsistantcy comes into play. Just like in most games, if one ref is under the goal and is calling every contact a foul then on the other end another ref under the goal isn't calling the same contact a foul then inconsistancy is occuring.
The only way you could solve this is make all contact a foul then every stick to it but then scoring would go up and defense would dissapear. There a fine line also thats why refs can make a 10 point swing in the game without anyone even noticing majority of times.
