I’ll wax the string and cables when it starts to get a dry look. As to the question, is the string all right? Most often the string will let go under the center serving where you attach the nock set at the apex. Normally the string will give you an indication if the strands are starting to go. If you are a right hand shooter and your arrow start hitting high right, it’s time to replace the string and cables. When strands start to break you will pick up speed due to fewer strands and impact high because the spine of the arrow is weaker with the increased speed.
