How fast should they happen? As fast as they will allow. That's the smart alecky answer, unfortunately. The output is based on whatever they perceive and whatever their constraints will allow. What you have learned up to this point determines your experience and how you perceive sensations. I could give somebody a suitcase carry and they do exceptionally well, recapturing all of the motion I'm trying to gain. Then I can do the exact same thing with someone else who doesn't have the same experience. They think they understand what I want them to do, but their perception of instructions is different. Their execution is different, their sensory inputs are different, and they fail miserably. Part of this is when you're interacting with somebody, you have to get to know how they behave through coaching, time, experience, and repetition. There are two types of constraints by definition in the literature: structural constraints and functional constraints. Structural constraints are how you're built—your archetypes, configurations, connective tissues. Functional constraints are the things that change that fast. If it's a functional constraint that is the limiting factor, those things change instantaneously if you give the correct input to get the correct output. It may just be a sensory cue through any of your senses. If you have the correct influence to produce the favorable outcome, you will get the favorable outcome instantaneously if it is one of those things that changes that fast. If I have a structural constraint, like a torn ligament, how fast can I change that ligament? Probably not that fast, because it's structure that would need to heal or change itself. Sometimes we have to do surgery to help with that. Structure changes slower, sometimes a lot slower than something that would be almost instantaneous. If I come up behind you and scare you, your heart rate goes up really fast—that's almost instantaneous. That's a constraint that fluctuates very quickly. If I say the wrong thing to you and you become defensive, that's instantaneous.
