I learned something from watching this. It also confirms what has been said on this forum.
Love it. His perspective sounds very Crackingthecode-esque indeed.
It is amazing how all these information seemed to have been available for decades but guitar community, to a certain extent, decided to “willfully” ignore all that and stick to a lot of myths because reasons.
This guy blows, and I like it. The advice about going fast once you’ve gotten passage under fingers fingers when learning speed reminds me of similar advice from local Italian maestro @tommo on learning/practicing from 2020:
“Go fast and clean it up later, tater”
-Shawn Lane, probably
@steve506 this info is getting out there finally for us 

Oh wow thanks for digging that out! Luckily I read it again and don’t regret writing it in hindsight 
I think our understanding is a little more nuanced now. There’s no guarantee that the “try to go fast” step will always work - in a nutshell you also need to go fast with a technique that is actually capable of going fast on the passage in question.
Classic example: DSX motion trying to play USX lick. No matter how hard you try it won’t work. So you either need to figure out how to do a USX motion, or you need to find a way to change the lick for DSX.
And so on and so on 
Yes! The whole demystifying work around guitar technique by Troy and others has been groundbreaking.
On that note, I think the ability to scope what your technique can give you is a major boost. Like, say you want to play some Yngwie but you play DSX so you should be aware of the differences in musical vocabulary and adapt (eg. sixes starting on an upstroke). Thankfully, that sense of awareness helps make things flow more naturally over time.
