This tool lets you follow the progress of an IFSC bouldering competition, and calculates the possible rankings given athletes' performance so far.
Go to the official IFSC results site, and find the page with the ranking you want to follow. (That is, a specific round of a specific category and discipline.) The URL should look like this:
https://ifsc.results.info/#/event/[number]/cr/[number]
Copy the second number (the one that comes after "/cr/") and enter it below.
