Thanks for filming these! I moved these to their own thread to keep the other one more on track to the “phone tapping” test idea.
This is a nice looking picking motion. It looks easy and relaxed, and far from the stringhopping attempts we often see. It’s also not slow, around 200bpm give or take. Varies between 195 and 205 approximately. I will remind everyone that this is for the most part as fast as I’ve ever played in any of the things we’ve posted, and approximately as fast as Michael Angelo Batio played in our first shreddier interview with him. Hard to believe sometimes but true.
The highest speed is actually basically the same in all these clips, with and without metronome. The metronome ones are just more even. As is often the case in the examples we review, you’re not really playing along with the metronome. It looks to me like you’re mainly using it to get pumped and try harder. For future motion tests I might ditch the metronome and just focus on the getting pumped aspect. You could probably get the same result with some death metal in the backround. Maybe even better results!
The one thing that’s unusual here is the speeding up and slowing down. Whatever speed it is, tremolo doesn’t usually vary too much in tempo, at least until the end if you start to tire. So that makes me think that as relaxed as this is, there is another motion you can do that is more flat-out and will have a more typical even rapid speed pattern.
Have you taken the table tap tests in the new lessons? Those do use a metronome. Are they any faster or more even? Have you tried other mechanics like elbow?
I think given how comfortable and non-hoppy these results appear for you, some more experimentation may produce an even better motion.

I’m going to continue experimenting, but it made me wonder - How common is it for a player to systematically use more than one motion, depending on the string being played? (Regardless of the picking patterns). For example, a single-escape pattern using elbow for lower strings and wrist for higher strings?
(I’ve always got more stuff wrong with CTC than I do right, so no change there!), but the physical feel of that flexing and extending is hard for me to ignore and trying just the credit card motion doesn’t yield the same results.
