I looked at some of your videos. You are really cool imho! 
I don’t think this will apply to you, you seem almost pro, but maybe others can benefit from it or get inspired.
No matter if I start learn something new or already somewhat skilled, I use the same kind of approach. This goes with Guitar also and I seriously doubt my approach will change much over time.
As totally new to something, I want to get a roughly overview. How does it function. Is there a theory behind, how does that roughly work.
Next just get a feel for what and how and so on.
Then I try to get a sense on what to adopt and what to reject. That can save me a lot of trouble and time later, so I don’t have to unlearn a lot of bad habits, in order to get back on track.
As I progress, I start extract the key points, the crucial points as in overall, but also specific on the route I want to go, if more than one available. With guitar it seem like countless routes. 
I always try my best to combine study and practice. They help each other. Also improve and refine one skill that is already pretty ok, can spill over, have a positive ripple effect on other areas, though being careful not to end up, only being able to do one thing really good. Can be a tricky balance at times.
As said, I try to find the crucial points. Al Di Meola gives here one of those crucial points. For me all 36 minutes are worth listening to. But the crucial point IMHO, is at 12:11, that section. So since I feel and see it as a keypoint, a crucial point, I put extra effort into getting good at it, perfecting it, refining it. It’s about rythm. Justin also very much emphasize this point. - 12:11 for Al Di Meola talking about rythm
PS. Edit. One more crucial point I have discovered, was from one of the Classical Nerds. If I have a point in a piece, where the chord shift doesn’t work or I have a lot of trouble exactly there, then he said, try look a chord or two back. See if the chord shift can be improved, by taking the chord before the problem chord, a bit different, so it becomes more easy to make the shift, to prepare for the next chord. He said it sometimes can be helpful to look two chords back and already there change the hand position, to ease the shift two chords later. Even as a total beginner I find that extremely helpful.
