How would it be more useful? How would you differentiate year to year when course conditions change? How would you determine that a crash in the pro race was unavoidable and a crash in the Cat5 race was avoidable? It would gather a bunch of data and provide fodder for the academics but I don't see what i would do to help improve the racing quality of beginning racers.

Someone asked if it was safer back in the day. I don't know, there were plenty of crashes back then. The difference that I see now is back then the officials knew you. You did not get upgraded on points, you got upgraded because the LA officials knew who you were. They actually talked to other racers and got their opinion of you before they upgraded you. You would not get upgraded if the only way you won was to ride off the front of the field. You had to win in sprints, and you had to win in breaks. When I returned to racing, USAC had lost my original 5 digit license number and all records associated with it. To them I was a nobody (and to most of you as well haha). I came back as a Cat5 because I had no choice, but USAC told me to submit an upgrade request immediately to the category I wanted to return to. The LA official responded the next day, with a personal greeting, asking me why I wanted to return as a Cat3 when she knew me as a Cat2 back then. The point being, she knew me. She would have made me a Cat2 right then and there, but I chose to earn it back with points.
