I never posted my more complicated version (all instances as of August with at least 50 MAU) since people were already having trouble with the first one ...

I'd say post for you. That's what !fedilytics@piefed.zip is for me. If other people like it, great, but I'm doing the analysis because I'm interested in it.

... if you’d like I can send it to you when I get a chance (I think I DM’ed you a work-in-progress version of it at one point?), or post it myself for you to reference.

I believe we chatted briefly about your next version, but I don't recall ever seeing it. I'd say post it, so I can link to it easier. I'm not sure how I'd host it in the wiki otherwise (not very familiar with that part of Piefed).

One thing I think including more instances demonstrates better is some of the ‘cliques’, mainly the similar defederation patterns between ‘flotilla’ instances. It also helps to show why the .zip instances are better for people who want less top-down defederation applied to them.

Sounds interesting. I look forward to seeing the new version :)
