@nitro1976 I hear you, but what I’m actually driving it here is, in my opinion, more valuable: Teaching individuals how to problem solve . The idea is, you can look at a passage and refinger it or re-organize the pick strokes and/or slants to play it in a way that is easier and/or gets you more of the timbre you want.
After a lot of study of the fretboard and CTC personally I feel comfortable with a lot of different refingerings and re-arrangements, so when I look at something I can’t play yet I have a lot of tools for getting under the hood and figuring out how to make it playable. Then if I see some skills that are needed that I don’t have quite developed yet, well then, I know what to practice.
