All weight is underside
Some additional thoughts:
I've seen people do the forms in my system, without any understanding of the underlying methodology. They were taught the forms more from a "collection" approach to learning. There was no teaching of the fundamentals and basics, as they are done in my system. Just the choreography of the form itself.
It's easy to tell when that was done, because even tho the choreography is "correct", everything about HOW it is being done is wrong. The rooting and stances and rotation and delivery of technique is all wrong. It's just some guy waving his arms about in imitation of our system. And as a tool for practicing and developing skill, it makes the form worthless.
You can train one style and only one style and see the same thing; You can train one style and only one style for years and all of a sudden realize you were not doing it correctly. The rooting, stances, movement and possibly the delivery (not sure about that one) of technique is all correct..... but the intent is wrong, the understanding of the forms as to what the applications really are is wrong due to improper intent.
As for the delivery; I am not sure if that would be correct or not since it could be correct in that it works and works rather well but it is incorrect based on what the style you are training is trying to do since you have had the wrong intent and wrong visualization due to having the wrong intent.
