Sylph taper - robert maulucci

I just picked up a South Bend Single Built Cross Sylph model that is a great
casting rod.  However, it is dramatically different in taper from the rod in
the taper archives.  Can someone explain this?  I thought that Wes Jordan
kept everything pretty close to specs.  Or else, is the taper archive rod
misnamed.  Anyway, if someone wants the taper here goes:
