The reliability of a bet is calculated with several different variables. Among these variables are for example:
- The percentage of the sure bet (unusually high sure bets decrease the reliability)
- Last bet date (if the last bet date differs too much, the reliability goes down)
- How well the participants’ name match each other
The reliability of a sure bet is meant to be seen as a guideline for you when you bet, but please be thorough and always check the validity of the arb yourself.
