Something I've noticed is that saddle height, or more accurately saddle to pedal spindle (or bottom bracket) distance, varies depending on your usual cadence, and what you do with your feet. The faster you spin, the closer you have to be to the pedals. On the other hand, if you pedal slower with long powerful strokes, you need more leg extension.

So it's not just a matter of how you fit into the geometry at rest, you have to be moving in a usual way and make adjustments with respect to that.
