Re: How Long and In What Manner to Great Mastery?
To clarify further using your hips as the primary generator for that kind of hitting it not going to work too well against people who have internal power and internal skill because the moment you shift your hips you will find that they instantly take your balance (probably without noticing).
Also, I do mean that people are hit and hit incredibly hard - so there is plenty of real force. It's just that the way we are doing it results in the weight of the body not traveling with it or bracing it so it is not easily taken advantage of. I have a good friend with a fantastically powerful 1 inch punch. But he braces to do it. It's powerful for sure, but it is way too committed in terms of structure - and the structural weakness it exposes him to if he were say fighting 2 people at the same time. He is an accomplished martial artiest. He now trains with Dan because aiki is so obviously better.
As far as that vector of typical weakness. I'm floored that it doesn't resonate with you. Think about shihonage. The uke is raised up on the line from anus to navel, then thrown down on the line from navel to anus. Kotegaeshi for example works the same way. There are a lot of other examples.
To be fair, I don't think that asking for more concretely defined terms is "all you are doing". I'm happy to clear up confusion. However, I think your observations and comparisons are very far off simply because you cannot comprehend the degree of power differential. Even if it is because of our terminology - it really doesn't matter. The question is what this new training means to the future of aikido - any other observations and analysis from so far off base is really just distracting and unnecessarily confusing when they are asserted in the declarative.
Hope that clarifies the issue(s).
