Normalization takes a value and map it to a number between 0.0 and 1.0. There are a number of functions that can be used depending on what the graph should look like. x is the value we have as input and m is the max possible value x can be. Graphs can be made with Graphsketch.

Linear: (100 - x) / 100

Quadratic: (100) - x^k) / (100^k)

Logistic: 1 / ( 1 + exp(-x) )

Logit: loge( x / (1-x)
