"And how do you know you've got the "right" dots? If you know the dots are right, then you don't need them."

That was what I was getting at in my first post about "write only memory" (which was partially empathizing with someone talking about a disconnect between brain and vocal chords). You know if the dots fit the memory of last nights session the same way that you know if a Beatles tribute band gets the opening chord of "A hard days night" even slightly different.
