The numbers are definitely higher than luckybancho's scrapes simply because not everyone has their achievements public. So any capture outside of SE is simply the low mean at-best. TEA clears is probably more so around 6-7%+ of the population.

We also have compared people who are eligible for ultimate by those who have the savage mount and that's another sample set to get a fuller pictures because there are many who have tried ultimate and don't clear. Maybe they had meaningful prog and their group blew up, many go on to find another group or pause their progress until they get time again. The beauty of ultimate content is it never expires, since you can't unsync or cheese it. There is always groups recruiting for any of these, at any point. So the numbers just will simply go up and up. You can't say well only 5% clear, not worth it. It doesn't work that way. Savage content expires every 6 months, the 3 ultimates never will expire.

Obviously the Japanese data centers take raiding much seriously than NA/EU combined. Gilgamesh and Levi have always been NA sever standouts simply because the hardcore players migrated to these servers before XPF ever existed. Regional perspectives on the game have always differed, it's just a fact and people still have this bubble mentality that raiding is just a small part of the game yet every JP server has near 30% clear rates of savage.
