I guess the string stretch along with the combination of the loop appearing to be longer than it was (stretch also) it would make the difference but when he measured me with their " measuring bow" I was shorter. I had oringinally measured 33" and now acording to them it' s 31.5" (i" m 6' 6" ) I' m going to do the nose to string and try to use one of the other one or two reference points you guys pointed out and hopefully it will tighten my groups. I just wished they had measured me right the first time because 31.5 would had given me alot more options on picking out a bow! This will be my third year bow hunting and I love it but my bow had never felt " right" maybe it was because it was to long all the time? I hope so.
Thanks again everyone
