Yea, an adult 4.0-4.5 who hits moderately hard with moderate to good spin will get 5 to 10 quality hours out of a good poly like SigPro Hyp. You can get another 5-10 hours of practice time but there is a big difference as it will not have the same snap back attribute as new poly. It kind of feels dead, flat or more muted after the first 5-10 hours. If you hit harder with heavy spin, you'll get even fewer hours. I play SigPro Hyperion all the time and that's my experience.
