I’m not a fan of this because of repeatability. Hideki has even shorted has pause considerably. I think a player at his level can get away with it (hard to argue with his results), but for us “mortals” I just don’t see it as a viable route to take.
However, perhaps doing some exaggeration during your practice sessions can help smooth out your transition while you play. I have somewhat of a “violent” transition and using the orange whip intermittently and working with tempo beats has helped. Just my $0.02
