The movement taught in forms is functional. For the specific version of the attack it's taught to block, or the specific opening it's taught to take advantage of. For variations of that attack or opening, the attack or block in the form has to be modified.
If you throw a punch at my sternum, the inside middle block, as it's taught in forms, is an excellent counter. If you aim at my nose, I'd better modify it.
What I see here is that not only do you not understand forms, you're also doing the movements within the forms wrong. The inside middle block I mentioned above is a fine example. If you're punching to my chest, I can counter by doing the movement exactly as its done in forms. Exactly. Honestly, I expect a 5th or 4th geup student to have a better understanding of this than you're showing.
