Seriously though, if you rip fibers, now matter HOW adequately you rip them, if you don't let them heal before ripping them again, they will not grow. There is a genetic exception to this rule for a trait that I posted for c-ditty a while back. Other than that, I would say there's a balance between efficient catabolism of the fibers, and the recovery that allows the anabolic reaction to that catabolism, that are equally important, IMO.
