However, this did raise a few question considering the usage of Elo in general, especially in football. How trustworthy this actually is, I won't comment on, it's just for curiosity.

I had in mind to implement a Elo-rating to find out teams/athletes most dominant in their field to be able to compare, let's say, a hockey team at it's prime to football and see who was actually 'better'. It's actually a lot of fun, having a history of my own in the competitive field, but also quite useful when learning web scraping and finding out about all kinds of libraries that make my life easier in terms of statistics and visualization. I'm a student and recently began a project gathering and analyzing different sport results and the teams behind them.
