Trying to do RDT DBX with 3 notes per string riff

Hi, this is my first time trying a TC. This is a video of me attempting a 3 notes per string "riff", but the riff is just open strings, so this speed (or lack thereof) is all my right hand, left hand is not involved. I would like to know whether what I'm doing is stringhopping (likely, because I can't get much faster than this), or properly RDT DBX. I would also like confirmation on this: if I want to do this type of odd-numbered note-per-string riff, it would be with a double escape motion like RDT DBX correct? Watching the videos on RDT though, I'm really not sure how I should try to evolve from this stringhopping to RDT DBX, assuming what I'm doing is stringhopping.
