Moving the saddle fore and aft isn't a proper adjustment to get your cockpit reach right.
The saddle should be adjusted in for height and fore/aft to get your knee(cap-front) in the right relationship to the pedal spindle. Once the saddle position is adjusted in it becomes a constant. The front end of the cockpit is then adjusted via the stem height/angle/length in conjunction with bars that have their own rise, reach, drop, and sweep characteristics.
There are fitting guides on the web that'll outline the process..
