I honestly can't see what you're saying. It's not like studio clean or 600th try of a 17 year veteran with a $5,000 computer simulated amplifier clean, but I wouldn't say that it's detrimentally sloppy either. The lick doesn't really produce a memorable melody when slowed down, as it's meant to...
"Apply this to all of the other scales you know that are 3 notes per string. This is why I’ve learned as many scales as possible in that formula because it is extremely conducive to Eco picking."
This lick that I developed employs multiple 3-1-3 patterns. I'm not sure how 'musical' it is theory-wise, but I obviously didn't play a pentatonic-based lick, as he stated in the lesson video that the 3-1-3 pattern can be played in non-pentatonic variants.
