Compares average flight time to average departure delay, scaled by average distance

This project offers an in-depth analysis of the performance of countries in the Paris 2024 Olympics, moving beyond the traditional medal count to explore alternative frameworks and metrics for assessing success. The analysis begins by scraping and tidying medal tally data from the BBC, presenting insights into the performance of the top nations. Various performance indicators, such as medals per capita, weighted medal counts, team efficiency, and economic factors, are introduced to provide a more balanced and equitable comparison of Olympic achievements.
