You might be right about the loading zone being quicker, but you lose a lot of time just setting up for the dash. Turn around, lock on turret, slowly walk backwards through the door, dash VS shoot ice door, morph, boost, profit. If you disagree then you should keep testing though!
I've found a new dash, I don't know if it saves time through. It's an slight easier way to get the early energy tank in the Main Plaza. Stand to the left to where the energy tank is and lock in to the bridge, Then do a height gaining scan dash and you should hit the tank. I'd upload a video if I had a Digital camcorder. I'm thinking about getting one.
