REPLY: Snake-eyes is correct that you're never going to get 100% consistency since the participants are part of that chronically inconsistent machine known as the human race. However, there is a statistical tool that can measure the degree of variance within the data and begin to point out where there might be need for process improvement (maybe "training") above and beyond the question of individual judgement. Four of the crews lie in an area known as "outside of the control limits" for the data. That is, they lie more than one standard deveiation unit away from the average of the data. The two highest and two lowest fail this test even though the two lowest (Kukar and Austin) are very close to being in control. If all crews lay within control limits, you could justifiably say that individual judgement might account for the variance. That they don't says that there's something more at work here than judgement. There might be some fundamental differences in what philosophies these crews use when considering fouls. (Note: Humor me...I was a statistician in a prior life!)
