I have 28" draw modules on my ARon the middle post which is 28 even and my arrows arealittle over 26.5" from nock groove to insert and they sit right in the middle of theriser window cut out.Maybe the module and the bow was marked wrong? I have wondered that myself?
It depends on where the manufacturer is measuring the draw length at. If they are measuring from the string to the front of the riser, that may explain the 1.5" difference you are experiencing.
