I really relate to this!
I remember when I first started practicing scales 10 years ago (with no knowledge of gyspy jazz) I found ascending them really easy but struggled on the descent. I slowed down and realised I was economy picking on the ascent (didn’t know what that was called at the time) but awkwardly alternate picking my way back down.
In hindsight, that probably meant I was using an USX motion but instead of accepting that as a solution (like perhaps Yngwie did) I saw this as wrong and made sure to alternate pick everything with little to no progress
