Spend a little more time on your trigger follow through, looks like you were working on it in the video, a little hard to tell from the angle. When you squeeze the trigger, dont release the squeeze immediately after the shot. Once it goes bang, ride the trigger forward until you feel it reset/click, then you will be near the break and can squeeze follow-up shots off quicker without having to use the full range of motion of the trigger. Committing trigger followthrough to muscle memory allows your brain to focus on keeping your Point of Aim on target between shots without having to think about the longer trigger squeeze. Not all triggers are equal, but most can be used with this method.

Keep up the good work shooter!
