Re: "Irimi" by Ellis Amdur
Graham, of course you are entitled to your own decision and opinions on the subject for sure.
In my experiences dealing with real people and real scenarios that are hell bent on really harming you, I have to say I have found that Ellis' analysis on irimi to be spot on with current military teachings on the subject for both the U.S. Army and the Marine Corps.
To be honest, I am actually fascinated that just about everything I have studied that is founded on good, solid koryu to be as relevant today as it was hundreds of years ago.
Of course, tactics aside as they constantly change and adapt based on the application of technology.
However, and the fundamentals, they are the same.
You can continue to move off line as you wish if you have found that works for you....maybe it is semantics and we would be able to get together and see we are looking at the same thing though using different words/paradigms to describe.
For me though, moving off line does nothing to affect uke, it does not disrupt his movement or motion...it only delays and when you consider how the brain works, looking at the concepts of Hicks law especially you simply do not have in reality much time to make a choice and hope that it is correct. the law of this process of movement dictates that you are not in control of the situation and nage is. that in and of itself means that nage can process movement and choices faster than you. So you may get lucky on occasion and move off line correctly.
The odds are based on the relationship between uke and nage that nage will move more correctly than you can ever move. So you have one chance to change the situation and that is to irimi as Ellis has described. For me it is about Odds and I have found when I move as Ellis has described against a bad guy either in reality or training that I fair much better than moving off the line.
