As has been stated, it really is as variable as how many times you will see the color blue within the next hour... I have literally had a 1.5" long, pencil's diameter cutting put out two fruit, two weeks after beginning to root.
This Black Madeira is four times the diameter that that cutting was. It was dormant prior to grafting it six days ago, and it started swelling the fig yesterday. I'll remove it to put it's energy into growing, but it's just to show that there isn't really a limit on their time frames.
