Good point rickybails about the saddle-BB relationship. I agree it's the most fundamental dimension of fit, and one that's often ignored. A good reminder to me that I should get myself a pro fit to nail it down. I do know that I like my saddle further aft than most folks do (one reason the Swift's slack seat tube angle appeals to me, also one reason I despise Brooks saddles) and that I can put out more power that way, and thus I've realized that the standard KOPS method is BS for me -- but I don't know the exact measurement that's ideal. Really should spend some money to get that figured out.
