Sadly I don't notice much of a change in my position. It seems like in the new video I am back a bit farther (As per the suggestion) but I don't notice anything radically different. I didn't move the seat too much in either direction (Incremental movements I would assume are best)
One thing I noticed since it was mentioned was that I certainly feel like I might be stretching out too far for the bars. I can actually drop myself pretty low without any discomfort (I can place my head on the garmin unit with almost no stress on my back, finding a good spot for my hands is the challenge). I have always had a short torso for my legs so perhaps a 56 frame actually has too long of a TT with a regular stem for me?
I can say that I didn't pull up on the pedals as much when I was focusing on "down and out" as you suggested. Problem I seemed to find while doing that was that it was hard to move my hips further back while keeping a comfortable grip on the bars.
