I just had my bike fitted, and the main thing we changed was the seat angle, tilted the front down a little. The fitter I worked with first measured things, but was very interested in what I told him about how I felt when riding the bike. We might move the seat angle move after another ride. He measured my back angle and said the bars should probably come up just a little, but since I spend long periods of time in the drop and feel comfortable there even for over an hour at a time, perhaps we should just leave it. We even discussed lowering the bars so I would spend time on the hoods. In the end the peliminary fit that was done when I bought the bike two weeks ago was good as far as seat height, distance from bars, the basics were spot on. Now it's more about me telling him what "bothers me" after long rides and see if we can tune those issues out with little adjustments
