If you do legato hammer-on and pull-off chromatic runs and scale runs too, plus tapping, arpeggios, and sweep picking, you'll clock out even faster! I'm just getting into all that after working on straight picking for a bit.

It takes a bit to understand the metronome. Starting out in slow chunks works best for me. Then, I just relax and let my body take over as I speed up. The hand is quicker than the eye. After watching my fingers the first few times, I learn to play from feel, not by watching my fingers, I read the tab while playing instead. After memorizing the tab, I like to sit back with my eyes closed and see the patterns in my mind's eye while I play. After a lot of practice, then physically watching can be done from an objective point-of-view, fun to watch..."I did that?"
