Here is a Google sheet ranking the LSUs (longest standing untied WRs) of GE 1964, which tracks both all-time and currently standing LSUs, and all-time untied duration per level: https://docs.google.com/spreadsheets/d/1mTw9HXijCkwOTXRq3oVl0qTD48He9GS9mNiFO9Dlzp8/edit?usp=sharing

I tried making this as automated as possible, but it still needs to be updated manually for new runs added to speedrun.com

It's great to see that you've put in the effort to create and maintain such a record-keeping system for the speedrunning community.
