Yes, scientifically speaking, walking is falling and catching yourself.

this thread got silly

What is silly is thinking that you can do any physical activity that requires locomotion and keep your weight doing anything except constantly shifting from 100% on one leg to 100% on the other leg. What's funny is that you have entire sub-systems of WC that are supposedly based on 70/30, 100/0, etc, when the only time you could have that would be if you never moved.

I agree, and well said!

I/we dont talk in 70/30-60/40 bs either, I mentioned that earlier...im not arguing either.
We talk of fighting , motion, angling....who fights statically ?
we walk like a pendulum. The problem is we do it badly.
A pendulum is a device that transforms kinetic energy of motion into gravitational potential energy and back. As it moves through the bottom of its arc, the pendulum's velocity and thus its kinetic energy— mass times velocity squared divided by two, or mv 2/2— reach a maximum. At the top of its arc, the pendulum slows to a stop, but at that point the potential energy— mass times gravity times height— is at its peak. As the pendulum falls back down, potential energy is converted back to kinetic energy. In a good pendulum the conversion is close to 100 percent, with only a bit of energy lost to the friction of moving through the air and that of the bearing from which it is hung. One nudge, and a pendulum keeps swinging a long time.
With each step you walk, you yourself become an inverted pendulum: You pivot around the foot that's on the ground, as if you were using that leg to pole-vault, and your center of mass, somewhere in the belly, describes an arc. As you plant a foot on the ground in front of you, the ground exerts a force back up your leg that slows you down, and you continue slowing as you rise up on that foot to the top of your arc. At that point your kinetic energy is at a minimum— but your potential energy is at a maximum. As you fall forward into the next step, that stored potential energy is converted back into kinetic energy, and you accelerate again.
"If the body were a perfect pendulum— if it could convert the kinetic energy into potential energy and back without wasting a calorie— walking would be nearly effortless," says Heglund, a physiologist at the University of Louvain in Belgium. "But you're only 65 percent of a perfect pendulum." In other words, 35 percent of the energy for each step has to be supplied afresh from the food you burn. Fish and birds do better: They burn less energy per unit distance than we do, even though birds are fighting gravity all the time, and fish have to fight their way through a dense liquid. "So why are we sweating? Where's the work?" asks Cavagna. "It's work we're doing against ourselves. It's a lack of coordination."

That measurement refers to a stance..a stance in a form.. The stance in the form teaches a kind of stepping, loading (receiving force), compressing that force (storing power) and alignment. Many of the stances are seen as some kind of static "thing" you should always do, this is not correct, it simply represents a mechanic, a tool or transitional (extreme) position, dynamic or tactic..
And as an example the CK step does a remarkable job of shortening that "time of unbalance" and how to recover it.

That's true.. but is the bik ma step walking? Is there really a point of "falling" during any part of that step?
There is centered movement, balanced motion and unbalanced, off centered motion... The former is the goal...

You can use your body falling to pull your opponent6 down with you. If you can catch yourself and regain your balance back, you have just execute a perfect throw.

if WCK is like this then WCK is over.
These shifting stuffs have developed into a point that one is no longer human but trying to become a robot or woodern dummy or not nature at all. thus, this type of art will not be able to flow.
Just to be real real real honest, this type of stuffs is exactly why the short Jin of WCK 1850 lost.

To fajin one needs that unbalance to accelerate and propel out.
and one purposely did that because that is how one control acceleration and also not standing there to be grap and take down.

IMHO
who cares about bik ma or this ma or that ma? those stuffs are just tools for training to explore one's limit or boundary in movement. WCK is not other nam kuen.
EVery fajin is a falling, using the drop the weight and let the center of gravity force to accelate one without using any muscle or big horse stance step. it goes down accelerate and propel out when the opponent contact one's body.
What centered movement? what balance motion? who care about balance motion? using the impact of the opponent to balance the motion. a self balance motion is a waste of energy and make one stuck.

how i presently learn (Ng Chun Hong - WSL/Jui Wan) we are taught probably around 80%-20%
when we strike we do not transfer like a boxer on a 50-50 (although i can of course see that benefit too). we always drive through the heels of our back foot.
different strokes for different folks...

Apparently most people who practice WCK don't fight at all.I/we dont talk in 70/30-60/40 bs either, I mentioned that earlier...im not arguing either.

No we don't -- we do it extremely well. We're able to walk around for days at a time without falling down!we walk like a pendulum. The problem is we do it badly.
More theoretical nonsense.A pendulum is a device that transforms kinetic energy of motion into gravitational potential energy and back. As it moves through the bottom of its arc, the pendulum's velocity and thus its kinetic energy— mass times velocity squared divided by two, or mv 2/2— reach a maximum. At the top of its arc, the pendulum slows to a stop, but at that point the potential energy— mass times gravity times height— is at its peak. As the pendulum falls back down, potential energy is converted back to kinetic energy. In a good pendulum the conversion is close to 100 percent, with only a bit of energy lost to the friction of moving through the air and that of the bearing from which it is hung. One nudge, and a pendulum keeps swinging a long time.

Yes, bik ma is stepping -- you move your feet for locomotion. And anytime you move your feet or body, you lose your balance. There is even a kuit which specifically addresses this: Dik Yaat Yee Dong, Jung Sum Yim Hong - enemy shifting/moving 'balance is already empty'.
You don't need to focus on "centered movement, balanced motion" and it doesn't help to focus on it -- it is better to focus on the performance of the task at hand, and your balance, centeredness, etc. will take care of itself.
