    Vig win%
    Anyone have a table of the necessary win % needed to win units at incremental vig values
    i.e.
    You must win ____% on lines that are
    -110
    -120
    -130
    -140
    .....
    -250
    .....
    -400


    As well for odds that have 2 outcomes
    I know that -110 & -110 is a 10 cent line

    how would calculate that for a 3 way wager that lets say is
    +105 / +200 / +260


    Appreciate the help

    Ex A.
    for a 3 way wager I found an equation

    Vig = 100* {[ (1/p + 1/q + 1/t)-1 ] / 1/p + 1/q + 1/t}
    pqt each represent the decimal value of each outcome

    If thats the case then
    V = 100* {[1/2.25 + 1/3.5 + 1/2.75]-1} / [1/2.25 + 1/3.5 + 1/2.75]
    V = 100* 0.085752
    V = 8.5752

    Ex B.

    for a 2 way wager its
    Vig = 100* [1-(p*q/p+q)]

    lets say -130 & +110
    or 1.77 & 2.1

    V = 100* [1-(1.77*2.1/1.77+2.1)
    V = 100* [1-(0.9605)
    V = 3.9534

    What conclusion do you draw from this vig figure?

    in A is there a 8.5 cent fee on these odds

    where in B there is only a 3.95 fee?

    This would assume that the 3 way wager has a markup of nearly 4.5 cents of vig?

    If anyone can help me make sense Id appreciate it
