Further attempts at sorting out best motion

This is really a follow on to the earlier technique critique at https://troygrady.com/dashboard/tc/495/ although that technique critique was closed before I had time to upload the requested videos. (So it may be worth referring to the old critique to see what has been done before, especially if a new instructor does this critique. It was possibly worth starting with a fresh critique, anyway, since there were a lot of picking related videos on the earlier part of that critique as well). So I have videoed the EVH-style and Di Meola-style tap tests for the longer time and without a metronome. Also, using a mouse wrist rest as discussed on the earlier technique critique. I've also uploaded a new video of the elbow tap test. (Videos of the other two motion tests are on the earlier technique critique; but for a relatively short duration and with a metronome.). Anyway, still trying to sort out my best motion as I was in the latter part of the earlier technique critique? Also, I have another question - is it useful to practise these motions much - apart from the occasional video to upload? I think it was suggested the motions are fairly basic to avoid some of the other complexities with picking and guitar playing, and are normally fairly easy for anybody. On the other hand, I think Troy suggested that he had found practising the forearm motion away from the guitar to be useful. (This feels fairly abstracted from actual guitar playing at this point which I would quite like to get back to.)
