Encounters aren't everything

That's simply because of its final fight. Midas's first three fights were comparable and easier than Gordias, for the most part. You see a lot more clears in Gordias because it became easier to overpower it unsync'd sooner, as it has nothing as cockblocky as Gavel (Nisi kinda close though). That, combined with the fact that they've never nerfed Midas's bosses afaik, while they at least nerfed Living Liquid at some point = more Gordias clears.

Also I wouldn't say that Creator was a severe nerf to Savage difficulty. It was Savage difficulty without any stone wall mechanics. i.e. Late phase mechanics intended to wipe you for the slightest mistake on anyone's part. Whereas Gordias and Midas had fights with many phases, each phase ramping up as harder, and more intricate, Creator ramped up and then leveled off. It largely mirrored Binding Coil of Bahamut, blow for blow.

As already noted, they nerfed did A6S because it walled the raid community even earlier than Living Liquid due to its sheer difficulty. Furthermore, Living Liquid was never nerfed on content but only after Midas released. Likewise for Manipulator. So no, the survey data from Lucky Bancho was not bloated by subsequently nerfed clears.

As for Creator, not only did Yoshida deliberately say they scaled Creator significantly lower due to how poorly received both Gordias and Midas were but looking at the fights themselves and it's a night and day difference. Alexander deals noticeably less damage, has significantly less HP relative to the ilvl and the mechanics are more forgiving. On the whole, it's a massive step down from Brute Justice and Manipulator. The same can be said for 9-11 but not to the same extent since the differences between each comparable turn weren't as notorious, Living Liquid and pre-nerfed A6S nothwithstanding.

Regardless, I didn't say Midas was an inherently worse tier but rather the least cleared. Between it's mechanical difficulty, especially Brute Justice, pre-nerf A6S and Gordias, the raid community was completely burnt out. Hence why they completely changed focus from Creator onward.

You said to this day, and I assumed your data was showing all clears done between now and then. Not just ones done while raid tiers were current?
