I've been watching these runs quietly. The game itself isn't that great for tasing, but not terrible. I do find it entertaining in a staring-at-a-car-crash sort of way.
You have certainly improved your movies a lot. I decided to try the game myself a bit and saved about 3.5 seconds
in the first minute, up to when you enter that door with the hand over it, right before the first "boss" person who shoots out a tv. I have one less bar of health than you do, but you end the movie with 1 and a half bars of health so that theoretically shouldn't matter. And I'm positive my movie can be improved quite a bit actually, ending faster/with more health -- damage boosting seem quite helpful.
So, not to belabor the point, but you should definitely post WIPs and stuff before going to the workbench... I certainly wouldn't mind seeing another improvement on this, especially now that I'm getting familiar with it ;)
