I believe in the numbing points. Kirk numbed my arm up last thursday while we were working controls.
Pressure points are good to just get in the habit of grabbing on your opponent. Most weaken the muscles a little bit, makes them easier to manipulate.
As for pressure point striking sequences... Seems like youd get hurt trying to land a few in a row appropriately on a resisting opponent.
"In choosing your dwelling, know how to keep to the ground.
In cultivating your mind, know how to dive in the hidden depths.
In dealing with others, know how to be gentle and kind.
In speaking, know how to keep your words.
In governing, know how to maintain order.
In transacting business, know how to be efficient.
In making a move, know how to choose the right moment.
If you do not strive with others, you will be free from blame."
-Lao Tzu, Tao Teh Ching
An eye for an eye leaves the world blind.
