I can't resist!!
O-sensei said it is NOT about timing:
"It is not a question of either ‘sensen no sen' or ‘sen no sen.' If I were to try to verbalize it I would say that you control your opponent without trying to control him. That is, the state of continuous victory."

He also said it is his "firm belief" that it's time to think aiki instead:
"Takemusu aiki is a service we offer in order to protect the worlds in which all Universal activity occurs, that is, the three Worlds—Appearance, Subconscious and Divine—and help them to harmonize with each other and flourish."
Whooopeeee!! Well he was just a crazy old bunny after all.

Well, I guess no one says you have to do Takemusu aiki. Maybe what you do is all about timing. That's fine for you but it is not what I do.
Just kidding around Tony, that was another paraphrased O-sensei quote. Carry on. Bait always looks yummier than regular food..
