To me it looks as though you are starting to stop your momentum before you release. At the point of release you should be at your peak momentum and then worry about slowing down. If this doesn't make sense it's because I'm tired and doing tax stuff.
Edit: I rewatched your video. What I was talking about occurred in the second shot. The first shot your speed seemed excellent.
