Sounds like it is time to twist up a new string. If you can't twist the string enough to get in factory specs for brace height then it is the wrong length. Don't know that you would hurt anything shooting it braced to low just get more forearm slap and not good arrow flight? If it is a flemish twist string you should see a noticable difference in brace with about ten twists or so. Maybe your string came untwisted some during shipping? just a couple thoughts for what they are worth.
