Calculating Difference in Vig

[miniuser]

ok, i know you need to pick at 52.38% or better to beat standard -110 vig...but i don't really know where it comes from, or how to calculate what % i would need at -130, -150, etc....can someone help me here?

You have to win 110 out of 210 to break even, so 110/210 = 52.38%. Just calculate any negative odds the same way (odds/(odds +100)) to find break-even percentage.

So -120 = 120/220 = 54.55%
-130 = 130/230 = 56.52%
-140 = 140/240 = 58.33%
-150 = 150/250 = 60%
...and so on
