Oh god, I loled so much at you choking Uke at frame 130 of mediocre.
Basically, you use too much grab, and make it too easy to see when you are struggling with dismembers. If you are trying to decap uke with a punch, and it fails, rather then continuing on with a second punch or something to that effect, you should edit the punch until either you get it to work, or you figure out a better way of approaching the attack. Work on your flow.
