How to use the No-Vig Fair Odds
A no-vig calculation removes the sportsbook margin and normalizes both sides of a market to 100%. The result is a cleaner estimate of the market's fair price.

Formula and assumptions
Fair probability = side implied probability / total implied probability across all sides.
This proportional method distributes the margin evenly by implied probability. Other de-vig methods can produce slightly different fair prices.
