RSI FAQ

The Relative Strength Index (RSI) measures the accuracy of a player's picks relative to how many picks were made. RSI is the best indicator of how well a player does.

RSI ranks each player using a Chi Squared statistical test to determine the probability of success relative to an expected outcome of 50%. A RSI ranking of 0 means the same results could be expected flipping a coin. The higher the RSI ranking, the less random a player's picks are, and statistically meaningful.The lower the RSI ranking, the more random a player's picks are, and less statistically meaningful.

For moneyline sports, (MLB and NHL), RSI adjusts the expected value of a player's picks using the actual odds. For instance, assume a player is picking all favorites expected to win 57% of the time. In order for their RSI ranking to be positive, they need to have a percentage ranking better than 57%.

RSI also shows you the difference between a 20-10 record and a 40-20 record. Both records are 67%, but the 40-20 record is much harder to achieve, and results in a higher RSI rating.
