I have a 30" draw length and had my bow set for that when I was shooting off the string. But, when I went to using a string loop, my anchor point changed and was 1/2 in further back. This just did not feel right. So, to compensate for the added loop length I had my bows draw length shortened 1/2" to 29 1/2" . My anchor point or hand placement was back to where it was when I was shooting of the string. It was comfortable again and I was satisfied.

I can see having a loop make up for 1/2" , but 1" , I dont know. Seems a little excessive, and I would have to agree with Rack on the possible problems that could arise.
