"Anonymous. Your weight is leaving the rear foot. You don't agree with picture three so we leave it out.The next move is four. How would you get your weight in front of the front foot"
By dancing picture TWO without moving my front foot so far yet. The weight is in front of both feet at the beginning of the action, not at the end. You keep trying to jump to the end (picture FOUR) and pretend like it is the beginning.
"we wont even bother about the knee, which will have to be over the toe to a point of imbalance and stay verticle and then to fall or catch the weight without leaning forward."
The knee is not over the toe, it is in front of the to. And the body is perfectly aligned over the knee, with no leaning of the body, only an incline of the shin - if you still can't see that in picture two YOU ARE BLIND.
"To say imbalance is to be either leaning forward or backward."
ABSOLUTELY WRONG. Imbalance describes only the position of the center of mass relative to the supporting feet. It says nothing about the body orientation. Most imbalanced positions critical to dancing, like that shown in PICTURE TWO maintain VERTICAL ALIGNMENT of the body.
You've been fighting that idea so long that it is clearly not a failure to understand, but a willfill intent to pretened that you are stupid. The evidence is in front of your eyes - if you had any interest in learning, you would have now admitted that, regardless if it is a way you wish to dance or not, it is at least POSSIBLE.
"To catch the weight means like the feet are trapped and the body is falling ahead of its point of balance."
Catching the weight is a key skill taught by all good teachers. The feet would remain trapped only so long as their knees do not bend to let them move through - so the feet do not remain trapped. Falling ahead of the point of balance is precisely the GOAL - it is how humans have been walking ever since we came down from the trees.
