2/4 Dots is an easy way to learn where to place our balance. If your balance is on the 4 Dot then the leg on this side is weighted and the leg that has the 2 Dot is unweighted.

However, this does not tell you whether we are referring to the right leg or left leg as far as the 4 Dot is concerned.

Since the teachings stated that 1 Dot and 5 Dot are the two points to avoid, I find it easier to think the balance three dots as Dot-L, Dot-R and Dot-C corresponding to :-

Dot-L = when the balance is on the left leg
Dot-R = when the balance is on the right leg
Dot-C = when the balance is between the left and right legs

So if we take as example the transition from Beginning Posture to Left Wild Horse Parts Mane the stance work and shifting of balance can be stated as follows :-

1) Beginning Posture (Dot-C)
2) Left leg shifts to beside right leg (Dot-R)
3) Left leg turns 90 degrees, shifts to open into forward left stance (Dot-R)
4) Weight shifts to left leg (Dot-R to Dot-L), rotate body to left

The simplification of 2/4 Dots should make it easier for those who are teaching the 22-form to a large group of people, allowing them to always know the balance should be.
