    I am looking for an expression (or mathematic formula)
    that when applied to a source value, it will yield a result value in the following relationship:

    SOURCE = 50, RESULT = 200
    SOURCE = 90, RESULT = 111
    SOURCE = 100, RESULT = 100
    SOURCE = 110, RESULT = 91
    SOURCE = 150, RESULT = 66.667
    SOURCE = 200, RESULT = 50

    I am basically trying to negate scaling in a project.
    This formula would apply to AE, as well as flame/smoke, so if you know the formula, platform agnostic code would be great!

    thanks!

    result = 10000/source
