For what it’s worth, my end of year Wrap Up says that I played it for 80 hours. I did all the side missions, but none of the time trials and only got 59% of the trophies.

As someone who played at release that sounds vaguely correct. I also found a random let’s play that gets to boklad on episode 63/90 so you’re about 2/3 through

Simple maths also say so approximately.

It will also depend on the style of play completionist, main story only, main+side, etc.

Actually I haven’t play FF XVI yet. So “I don’t know” will be my best answer.
