Center is a very useful measurement. You want the center of the "cheeks" of a padded saddle to meet your bone centers. You want the outsides of the saddle to match the outsides (or be at least 20mm wider in the case of a Brooks or other suspended leather saddle) of the sit bones.
This explains a lot!! Both the Specialized and Bontrager measuring things indicate I should be on a 145-ish saddle, which made no sense to me because it put the edges of my sit bones very close to the edges of the saddle. I measure about 120-125 mm center to center.
