Searched but didn't find anything in thread titles. I have always heard that a new racquet's first string job (or the first one after the grommets are replaced) will have an exaggerated tension loss due to the grommets "setting in." What are people's estimated (or measured) values for just how much tension is lost to virgin grommets? Do people compensate for this and string the first job tighter? Or string a dummy string, let it sit for a week, then cut it out and put in the real stuff? Or am I just being too compulsive?
