My comment regarding timing discussion in the context of unbalancing is that I'm working hard to improve it but it is far from decisive elements. I was a big fan of timing years ago. There are also styles aikido who base entirely their techniques only on the right timing.
What I discovered, that when I'm weak, sick, injured, tired, out of shape, very old etc my capacity of producing exact timing diminish drastically. So if the success of unbalancing depends only of right timing, under heavy circumstances I'll be always helpless. I need my gross motor skills be very well trained to not depend only on those very sophisticated ones.
that is why probably ikkyo is the most important and most difficult technique in aikido because it relies purely on timing. You can only make it work if the timing is perfect.
