Similar experiences here. I string a number of club players, they have no idea of what strings they hit with, bring in their racquet when string snaps, be it 1 , 2 years or longer, and say they want same set up, glad the string lasted as long as it did.I tell them it will hit different, and that they should string more frequently after 14-18 or so hours if poly strings, as tension loss and loss of strings properties, and that falls on deaf ears, and they bring it back again when broken. Now you say to restring after an hour, that is just not being realistic for the club hitters at least in my area.I don't even do that for myself, as Nat gut does hit well for me until it breaks, as I hit with a quality gut.Yes it looses tension just like any string, but it's properties of resilience and elasticity makes it still very much playable, especially when strung at high tensions.My brother I hit with, former D1 player, hits all gut high tension hits until string snaps, and that's a good number of hours, no arm issues same as me.
The USRSA when they do a string playtest, all racquets once strung are measured sbs with RDC when removed from machine and then 24 hours later without being hit. This number is typically compared to psg original, strung at 60 lbs. PSG has approx. a 9% loss after 24 hours with no hitting at all, and others are compared to that number, some less, many are higher percent.That should not mean that if you string and not use racquet in 24 hours you should restring it because of tension loss.
You can certainly get carried away with equipment, most thoughts should be with form and technique, and not over think equipment.
