TODO o Record historical error values with respect to popular confidence in each game. Important to measure accuracy of crowd and identify what biases cause the crowd to be wrong o Identify biases o Persistent biases (like home underdogs and other stats where people notoriously miscalculate their importance) o Temporary biases (maybe like hating on a team for some reason) o Last week bias (check if people tend to overestimate teams that won in previous week(s) and/or underestimate teams that lost in previous week(s)) o Streaks that cause people to miscalculate o Take close look at home underdog games since oddsmakers deliberately place the "wrong" odds to improve their payout (they take advantage of known crowd bias in favor of away team) o Measure velocity of picks (rate at which people are choosing home vs. away *at the moment*. Important to recognize when the market is moving in one direction, possibly due to new information)
