I realize this hasn’t been updated in quite some time, but I would also be thrilled if you come across the old spreadsheets! I’ve been trying to keep notes on the changes made by each editor for quite some time & somehow just now came across this project.
Regardless of whether you ever find them or ever work on it again, this is probably the coolest thing anyone in the community has done aside from the edits themselves. So thanks for taking the time to do it!
