Thanks for the video!
What I see is really nice technique, but it’s too clinical.
You’ve got great accuracy and approach with that ring finger, but the whole hand needs to be closer to the fretboard. The movements - any quick bass movements - need to use as little muscle/actual physical movement as possible.
I made this video showing what I mean with both ring and pinky fingers. Hopefully you can see what I’m getting at, and try and emulate it.
It’s had to play with this relaxed, close hand position until your fingers and hands are acclimated to this close, minimalist fingering work.
Play it slow, play it close!
