Kermit - just curious - what is your approximate sit bone width? Am I correct that the Glamour K Arrowhead is 140mm wide?

I am interested in this saddle, but a bit confused as San Marco has their own system called S.I.Z.E to find the appropriate seat - very unlike anything I have seen. Found info here:

Your saddle is listed a SIZE 245. My sit bones are approx 130mm wide - but according to their system this would put me in a SIZE 225 or 235. This would seem narrower than 130mm - doesn't make sense.

Any insight appreciated. Thx.
