How bad do you have to mess up to get a 929. Now you have me doubting what I have been told to be true. This score as you pointed out tells me that Coleman must have really hurt us? We did not have a full load of ships either I don't think. Dixon graduated the school, does it matter what his GPA was when he graduated?
929 means a loss of likely 3 points 39/42 = .9285. That was the closest I could get to 929 for one year and would fit with what you said about not having a full load of ships
