I figured I'd waste an hour today and play around with my fit and see how things affected power. I moved my saddle up about 5mm and forward about 1.2cm.
Using PE when I do my 90% SST intervals @220 watts, I saw a wattage of about 270 watts. Unfortunately, I figure a side effect of this is going to be premature fatigue due to different muscle use. I had everything marked on my saddle and post, and since I've been making gains in the current position, I don't want to change things too much.
I moved the saddle up 3mm and forward 3mm.
Edit: Is it a really dumb idea to mess with position like this when there are no comfort or other issues?
