Love this site.
The distance you should be getting is between (roughly) the center of one sit bone to the center of the other one. Easiest thing would be to find the insides, then scoot your fingers out a little. I did the play-dough method (search the saddle section), and rolled marbles into the dents and measured between the center of two marbles.
