Very Useful Overround and Probability Calculator

[Bitcoin Betting Guide]

I made a calculator where you enter the odds and it works out the book % and sportsbooks overround for any betting market. This means you can check if a sportsbook is giving you good value odds and you can check whether arbitrage opportunities exist across different sportsbooks. This is most useful on non 50:50 markets. I found this very useful comparing sportsbooks to see who has the best odds in general, not just on one particular market but overall
