Feedback on RDT with 3-finger grip

Hi team, I've been trying to adopt the RDT motion with 3-finger grip as suggested in my last critique, and I feel like I'm getting closer but I am not really sure I'm doing the motion correctly so I'd really appreciate your feedback on what can I improve and how the technique looks in general. For context, please note that I finally understood the "garage spikes" scenario when playing on a single string (before, I only associated it with moving between strings), and I've been trying to get the angle right and sometimes I get the satisfying feeling as if I wasn't using a pick at all but that feeling comes and goes and some days it seems like I have to re-learn the motion from scratch so my guess is that I am probably being inconsistent with my technique. Your input will be greatly appreciated. Thanks in advance, Steve
