2. There wouldn't be a difference between e.g. 0a's files, which are indeed great and, according to what you wrote, would always reach a ratio between 0.8 and 1, and files from users which are "ok", but still get only 1 comment + 1 like ( ratio = 1). Zeroarcanus would in the end be listed below that other user.
That's how your system would work.
No wait, it wouldn't even work.
