Which bookmakers' price boosts are honest?
Every UK price boost we can see, recorded the moment it appears and priced against the Betfair exchange at that moment. An honest boost is one priced above the market's fair price; most are a price that was cut before it was raised. This table says which bookmakers do it least. Today's boosts.

Margin = boost price ÷ exchange fair price − 1, at the boost's first sighting. Fair price is the exchange's own mid-market with its overround removed. A bookmaker is ranked only once it has 10 priced boosts in the window. Boosts on markets the exchange does not carry (bet builders, player props, correct scores) are recorded but cannot be priced. BetVictor, Parimatch and talkSPORT BET share one platform and one boost feed, as do Ladbrokes and Coral; their rows are the same boosts under different names. Full method.
