...Regardless, this is no reason to believe that you were able to respond spontaneously because of your aiki training.
There's no reason to believe anybody responds spontaneously to anything. It's a contradiction in terms.
By the way, "Technique, IMO." It does someone no good to respond with movements that don't work. If you are ultra quick at doing poor wristlocks, what good is it?
My point here is that these are advanced concepts, and I don't think anybody can put them to much benefit unless they have trained their body to do the techniques right FIRST. You don't get to be O Sensei by just doing what he did last. It took him 75 years to get that good.
