update on this for @joebegly
I have spent the last week trying get my single position 1 4 3 1 3 4 endurance up and it’s working!
I was out of town for several days with just an acoustic. I was out of my daily routine of doing these at 100 bpm 6/8 16th notes but still sat and did these sans metronome - even on the long drive.
upon arrival home, I can burst these at least 6 or 7 times without falling off. In fact, I was able to sustain the pattern over many more repetitions right off the bat. I was surprised I could do this cold.
I did this for five minutes and though fatigue set in, I’m noticeably better at this.
as a result, I do seem to in fact be more accurate on @tommo 's exercise and when playing moving down a single string in a scale with these three note patterns.
anyway. it’s working and bursting definitely helped.
