If you look at the instructions for Specialized measure device called the ass-o-meter...or something like that, sit bone spacing is suppose to be taken at the torso angle replicating the riding position on the bike. This is where much of the measurement error occurs. If torso angle is measured in a position other than what you ride, then your sitbones can be unsupported or conversely a rider can experience chaffing based upon being on too wide a saddle.
As you figured out OP, one size doesn't fit all. Many prefer a kick up in the tail of the saddle because this elevates the Ramus to make room for soft tissue when riding aggressively in the drops. A matter of finding what works in all positions which btw, can be a bit daunting to find the holy grail of saddles. Also saddle tilt can completely change the load distribution.
Happy hunting.
