This website ranks Celeste speedrunners by an accumulated score from all their Individual Level times, largely inspired by the-elite.net and mossranking.com. For the data source, it uses speedrun.com and its REST API.
It is pretty basic right now, by design. With enough interest, I can see myself investing more time to make it prettier and add features. And of course it is open source, you are free to submit your own changes via a PR. Here is the repository.
Each run is given a score based on the percentage of how close it is to the world record of that category, with a record scoring 1000 points. All individual scores are summed up for each player, resulting in their final point count.
score ≈ max(0, (1 - ln((e-1)*(runTime/wrTime - 1) + 1)) * 1000) Note: Farewell is considered an A-Side in this context. Also, Collectible runs use the Full Clear subcategory.
