Hey!
If you want a (very) rough estimate of your future CF rating and you're tired of waiting for a response in stefdasca's famous post, then wait no longer! I present to you this simple repo that performs logarithmic regression over your rating history.
This is by no means perfect, but you can help with that! Write your suggestions in the comments.
Edit: Apparently, as suggested by tgp07, you can run the code online.
