Correcto - who ever spends that amount of time to just try to determine the number of bad decisions made by managers before they cost games, might not be having a beer with me on the porch. Too much time in a dark room. I agree with you very much that there are many things that could come under the heading of "human element" that can not be statistically measured. Confidence, anxiety, stress, attitude of the clubhouse in general, as well as a feel for the game.
