    How to calculate average chalk layed in NHL

    Tinkering around with making an NHL model. Which is the best way to figure out average chalk in excel.

    I tried just to average all of them, but that gave me a number which is too low.
    Then made it into a number (-110 to -1.10) but that number seems alitte too high.
    Is there a better way that I am not thinking of?

    Convert each one to the implied win percentage and take the mean average of those.

    Implied win percentage of -110 is 110/210 = 52.38%
    There is a calculator here, if it helps. http://www.sportsbookreview.com/betting-tools/odds-converter/

    US odds are non linear. Convert to decimal or percent.
