    Turning a Positive Number Into a Positive for Probability

    Lets assume that team A and team B will play a match, and their powers are calculated like this:

    A: 20
    B: 10

    From this; we conclude that A has a winning probability of 66.6%, and B has a winning probability of 33.3%.

    Now let's assume that, using a model powers of team A and B are calculated like this:

    A: 8.36
    B: -7.15

    How can the winning probabilities of team A and team B can be calculated ?
    Please don't tell me to add +8 to both team's powers because it gives ridicilous probabilities. There should be a statistical way to find probability IMO. Does anyone know ?

    Thanks in advance.

    Hmmm, taking the square root of each number should do the trick... but that will require the use of imaginary numbers. Which should fit nicely with your use of imaginary handicapping.

    maybe the differences between two rankings (assuming power is linear)

    We need a lot more info your power ranking system to offer any guidance.

    any system that calculates probabilities like in the first part cannot have negative numbers as scores. if the negative scores are real, something is fishy with the probability calculation.
