The age of the tree affects the ripening times. A young tree will usually take longer than a mature one.
Whether the tree is in a container vs. the ground will speed up ripening.
Averages are just that. I have varietals that can mature a main crop fig in abt 60 days. I also have some that need abt 120 days.
Of course, there are other factors that can affect it such as horticultural practices.
