Argh, I wish I could find a citation right away but having trouble in search - while I get the example (memorize X amount of numbers) and discovering there&#x27;s an upper bounds is understandable. But what I had in mind was a musical instrument, in that there are a finite number of notes and how those notes can be played in a harmonious fashion. The study I saw, or think I did, showed that when performing a music solo some musicians were able to turn off the &#x27;active&#x27; part of thinking about the notes to play. It was some different mental channel. That would, to me, explain how a guy like Freddie King could play a song like Hideaway for 45 minutes with his band and people would enjoy it.<p>Quite a cool article. Lots to consider. Phrase around my &#x27;woodshed&#x27; was always &quot;Practice makes better&quot; though because perfect and guitars don&#x27;t really ever align.
