I have put 40+ string savers (babolat ones are good and slide, tourna ones don't slide really) and so far I'm at about 20+ hours with no notching. I think I could do 40+ hours which is great since I hate stringing.
Stringing lower in the 40s lets the strings retain some elasticity imo after 20+ hours, it's still feels decent I might string a few pounds more next time, or prestretch the poly (is that a thing)
