Data and source code for calculating user interest decay rates
By taking in data in the form of:
7/18/2018 star wars rebellion
7/18/2018 el grande
We can see how interest in certain games decay over time, given some sort of decay function. Each day of interest generates 1 point, and each day without interest decays by 5%.
An example walkthrough of this script can be found on my blog: https://svburger.com/2019/01/06/how-interested-in-this-thing-am-i-really/
