You need to scale your numbers with a logarithm or Laplace smoothing or similar. When your measuring quantities that follow power laws, using a linear scale or any linear combination will just give nonsensical answers.
Whats interesting is that they are already scaled logarithmically and normalized.. just there are clear as day differences between the currencies when it comes to their git stats. Especially when going across 600+ of them, I will look into laplace smoothing... seems interesting, or maybe the letter grading system may be too harsh? valuable feedback!
So made some tweaks to the algorithm with some laplace smoothing and some additional normalization functions... looks better!
