How many hours you listen per week tells very little. What arm and turntable are you using, are you buying new, or used, records, are they cleaned with a machine, and, if so, what machine are they cleaned with, are you playing primarily 33rpm, 45 or 78, what do you clean your stylus with, is it after each play, do you use Stylast on your stylus, or Groove Glide on your records? That said, an average lifespan for a radical cut stylus is, maybe, 1000 hours. But like tire wear, a whole lot of factors come into play.
Remember, if you replace your stylus too early, it costs you some money. If you replace it too late, it compromises your record collection.
