For many people I think that's too big an assumption to start with :D Given that your body position is the cause of most of the drag it's not something you can brush past. I was just trying to distil a number of the articles and forum threads into a simple list. Sorry if I derail your post...

My point I guess was that getting yourself to an orthodox position doesn't necessarily need to involve visiting an expert fitter. Just working out from orthodoxy what a good orthodox position for your body size is, and knowing trigonometry, you can often dial in a pretty good position with no more than the adjustments on your bike, or at the most a new stem and saddle.
