 There are other tipsters who provide equally respectable results through analysis of commonly accessible information.Some tipsters use statistical based estimations about the outcome of a game, and compare this estimation with the bookmaker's odds.If there is a gap between the estimate odds and the bookmakers odds, the tipster is said to identify "value", and a person who bets on such odds when they perceive not a certainty but a "gap in the book" is said to be a "value bettor".
