To make sure the selection is properly weighted according to the proof score, we normalize the contenderId to a number between 0 and 1, then take the logarithm and divide by the weight.

Since it is scale-independent, we can simplify by removing constants and use base 2 logarithm. Inspired by: https://stackoverflow.com/a/30226926.
