I compiled Glicko-2 ratings (like Elo) for sumo dating back to 1909. The goal was to provide myself with benchmarks for exploring sumo history by tackling these questions:

• Who were the best wrestlers at a given point in time?
• How do wrestlers from different eras compare at the same age?
• Which wrestlers define the eras of modern sumo?
• How impressive was a given tournament performance?

Data Sources

• https://sumodb.sumogames.de/, specifically /Results.aspx?b={id}&d={day}
• https://www.glicko.net/glicko/glicko2.pdf

Tools Used

• python/sqlite for data handling
• html/css/js, specifically d3.js, for visualization
• github/netlify for deployment
