I'm no expert on bike fit, but like Kano, I think the initial fitting is just a starting point. After that, you have to tweak as you go, figuring out what's best for your body and your riding style. For example, you might want to try raising your stem a tad.

I'm in my 50s now, and no matter how hard I work on core and flexibility issues, I'm afraid my back is never going to be what it was in my 20s, so I've found that keeping my stem a bit higher than my saddle keeps my back happy and keeps me cycling. Just a thought.
