Do we actually even KNOW how to get faster?

I understand what you are saying, but this “boring” routine you allude to can be 1000 different things for 1000 different players. Some guys put in 2 years of practice and they are shredding nicely, others not so much. (regardless of fast twitch capabilities)

I guess in the end though its a lot of hair splitting. If a person has decent speed capability and they are spending quality time practicing and they arent making TOO many errors, then they should end up pretty good.

My thing is, there is a VAST amount of stuff one might want to be great at:

scales and fragments (endless subject in itself)
pedal point stuff
sweeping (endless)
2nps stuff (to me,entirely different than 3 or 4nps stuff)
tapping
interesting harmonic content

in the end we have a finite number of hours to practice. Im “lucky” in that Im single with no kids and I only work 4x per week. So there is tie to practice. That being said, I want the most bang for the buck

That is what this other thread was about: Is there a master list of skills for picking? - #3 by hamsterman

I want to practice the stuff that has the greatest carryover to other stuff as opposed to spending many hours on some white elephant lick that has no carryover.

But even within that, is still HOW to go for that gradual speed improvement

I know in strength sports (probably endurance too) one doesnt simply go to the gym and max out every day lol. if there is a powerlifting meet in Sept one might start specifically training 10 weeks out and he builds to make his strength peak on that day

I understand guitar isnt exactly like that but one still wonders the best way to approach it. If my max speed on a lick is, say, a sloppy 200bpm, maybe I can do it smoothly at 188 but even then I cant last forever on it lol..it starts to get sloppy as I tire. in that case should one spend a ton of time “building a base” at 160 etc. Then as time passes one moves that base point up to 170 and he has almost guaranteed his peak speed capability will have increased too.

That is sort of how strength sports work so I am interested to know if guitar is in any way similar.

Something in me rebels at the notion that we have a certain preset speed limit. Yes I agree in theory but the problem is WE DONT KNOW WHAT THAT LIMIT IS!! lol People get stuck benching a certain weight for years and they r told they have reached their limit. Then they find some technique or mechanical thing or method and next thing you know they pass their “limit”
