What a thoughtful response! I won't do a point by point analysis, partly because I agree with many of your statements, and I haven't got across my main thought.
Let's deal with math first, because it is easier. You did not put your rote learned math into your subconscious, you put it into your "good old" usual memory. You replaced a calculation by a result and stored it as a typical memory to be pulled out when needed. If you pulled it out as part of a logical analysis your subconscious played no role. But this doesn't get to the heart of our discussion. The focus is not on where something is stored, but on how it got there and how strong was the recall path.
Here is the distinction I am trying to make, whether we use the words unconscious, subconscious, intuitive or whatever.
Having analyzed a problem - say playing a legato passage - and having formulated an approach to solving it - by overholding, say - the question then arises as to how to get into your memories the physical movements, muscle patterns etc that will enable you play the legato passage in the required way. I use "memories" to emphasize the complexity of the signals, pathways and destinations of the inputs to the brain. Clearly, much of this input does not involve the pre-frontal cortex and its role in analyzing, organizing and deciding. It happens in parallel channels without conscious direction.
However, let's say that the (simplified) solution is to practice exaggerating holding down each note until the next note has been struck. You can go about this in two different ways (or blend the two).
1. The pre-frontal cortex figures out a sequence of steps for your hands, fingers and muscles to make, and gives high-level guidance to the rest of your brain, your nervous system and your muscles as to how to proceed.
2. By guided experimentation you generate a large variety of inputs (though all of them within the overholding general solution) from your hands to your brain and let the brain select the best movements. Exactly how it does this I do not know, but we know it is a multi-path, multiprocessor approach with some sort of voting and pattern recognition happening, including the prefrontal cortex in a less dominant role. Probably the major distinction between the two approaches is the role of the prefrontal cortex: how dominant is it.
The problem with approach number one is how limited it is. The more you push through the prefrontal cortex the slower are the results, and the less complex the analysis. It doesn't utilize the amazing power of the other subsystems.
So the trick is to give each part of the brain its correct role. Our western approach to most problems over emphasizes the role of the prefrontal cortex. Very few students leave school with any FEEL for math, but all of the best mathematicians are intuitive and creative, and often solve problems then add the step by step proof later. Clearly they have highly developed technique and logical reasoning, but those alone would not solve many of the hard problems in math today. (Most people don't seem to realize that there IS any FEEL in serious math!).
So now I think we can arrive at a violent AGREEMENT.
Before we can improve a piece of our technique we have to analyze the problem, formulate a solution, and plan a way to develop the new technique. But sooner or later that broad plan of attack has to be broken down into thousands of micro-adjustments and integrated back into smooth movements. THIS cannot be done by the prefrontal cortex nor is there any part of the brain that can prejudge exactly what these adjustments should be. It only works as a sensory feedback loop, with an enormous number of interconnections. The issue can be stated as follows: is the prefrontal cortex (or any other part of the brain) getting in the way of this beautifully tuned system, eliminating inputs, forcing closure of certain paths, overriding signals and causing irrelevant muscles to fire etc.
I believe that the answer is almost always yes, and we need to cultivate habits and practice sessions that allow the core system to do its job with the least interference, thereby allowing the brain to store purer memories than otherwise.
Yes, these purer memories will contain their own problems, and unless used wisely may be worse than prior memories, but if generated wisely they can do the one thing that the prefrontal cortex can never do: find a solution in a hugely complex solution space, which (solution) though approximate has desirable qualities not otherwise found.
Many of Alan's ATM's in "Honing ...", are aimed at allowing the brain to experience patterns that would be shut out in the normal course of practice. Because of his studies, we have faith that these new patterns are useful. Probably some of mine are not.
I apologize for such a verbose explanation with such a simple result.
