That is kind of the interesting thing about the 7th Calamity in particular. Most of the calamities seem to have the type of impact the 8th Calamity did and was a full reset of civilization. However, in the case of the 7th, the interference meant Bahamut's Rampage was exclusive almost entirely to Eorzea and was only a temporary setback. It makes you wonder if Louisoix interference against Bahamut allowed the coming of the 8th Calamity sooner or as your stating if that was always the intention.

Due to the timescale of the Shards, it makes it hard to tell when the flood of light started from our perspective. For the First that was a 100 years ago but for the Source... it really is not clear nor do we know how long it takes for the Asicans to start these processes on the shards.
