The answer will depend greatly on the string you' re using. A well built string can long much, much longer than a cheap commercial string.

I put about 15,000 shots on my strings each year. It' s been my experience that most of the commercial strings are built so poorly that they either fail prematurely or creep too much. I was going through about 2 per year. Same material on a custom string, will perform much better and outlast the cheaper commercial strings, many times over. Now that I' m building my own, they appear almost indestructable, but I' ll replace them once a year, if for no reason other than they only cost me $5 to make and an hour of my time. Add in the fact, that my own don' t creep after the first day of shooting and that my servings hold up much better, and you can see why I' m a firm believer in making sure you have a very good string on your bow.
