Sportsbook Efficiency
Empirical sportsbook efficiency, measured by comparing de-vigged prices to actual outcomes. Close Brier scores the final line; Open Brier scores the first posted line. Avg Move shows mean |close − open| (points for spread/total/prop, fair-prob delta for moneyline). Lower Brier = more accurate pricing. Hit rate = how often the devigged favorite won.
