Annnd 2, very importantly, the Bahamut calamity revealed to the Ascians that calamities didn't require a full map-wipe (and therefore thousands of years). Rather, they could do Calamity causing massive damage but not reset humanity; they were planning to do calamity #8 (Flood of Light in Shadowbringers) about 5ish years from #7 (The Meteor project; some 5ish? 10ish? years pre ARR).
So, even if they DID need to do 6 more calamities, it could be easily done in like.. 30-50 years tops.
