I haven’t tried keeping any kind of benchmark so far, but I’ve been starting at the same BPM every time (85) and the patterns have been clean and more second nature with every session. I’ve been stopping at 95 I think, and my picking feels pretty warmed up when I start playing. Not only that, but I feel like it forces me to hold the pick in the best way possible (and location on the string) every time, I’m guessing because the double upstrokes have to sound comparable to double downstrokes.
I wonder if this has impacted my top speeds at all. The first time I did this, I was feeling some interesting things in my wrist / forearm (a similar “effort” feeling to playing a hard rhythm or lead line you’re not used to), but now it feels pretty effortless.
