Silvio Barbarico and Dante Moro Superfast Blitz

Superfast blitz: A superfast blitz is possible thanks to a few exploits in the game. First throw Dante near where he can fall into water. There is a spot east of where you fight him. Let the mercenaries fight him. Don't throw him too close to the water or he'll fall in too soon. Then climb into the shipyard and get into the water close to where Silvio and Dante will appear. When Dante drowns the scene will start and you will still be in the water after the scene. After the scene run to the nearby wall and do a double air assassination. I also did a blitz with throwing knives which was almost as fast.
Man nice work on these superfast blitzes!
hahaha! very nice job with delaying the drowning of Dante! this video is really well designed.
Thanks for the comments, guys! 
I tried different stuff since the video, and there's a way to drown Dante faster and easier while getting in place. There also may be a way to do a faster blitz (during part of the scenes you can climb up onto the docks, but not where you want to go because the camera view changes so that you're confused where you are when you appear after the scenes). So you can expect a video soon. 
You should be able to double assassinate Silvio and Dante from ground level and shave off some time. They're close enough together. You just have to line it up precisely.

I saw that in Kill Them Again Where They Stand, but they're so far away you have to line it up pretty good. I am trying a faster way (you can climb up the docks during the scenes, but it's hard because you can't see Ezio and don't know which way he is going, but if your successful you can probably do a double air assassinate before they "stand". I'm currently trying to do that, please be patient, everyone).
aurel, any update on this superfast blitz?
I'm glad you asked. I tried before for hours, gave up, tried a little bit more some time later, and now who knows when I'll try again. The thing is you can climb up the docks during the scene, but you can't see where you're going, so it's hard to climb in the right spot where you want to be. A few times I managed to get it right, but when I tried to air assassinate them both I only got Sylvio because he was so close. My idea is to lock on to Dante to get them both. I also found a better way to drown Dante without waiting. This is going to drive me to insanity if I don't get it.
