In my view your comment are not harsh . what you said is completely valid . how ever for me it is an observation because at least after all how we really judge our equipment is by playing and not technically by measuring . but all said please take this comment with a pinch of salt .
I don't want to derail the thread or anything but what are the synthetic strings made of anyway?And are they really multi-fillament or just one solid wire? I image anything but the highest-end materials would elongate pretty much. Dyneema (or spectra in the US) has incredibly low stretch (I think like 3% before breaking) and is incredibly strong,A 1 milimeter thick string can hold up to 210 KG! Sorry again,asking so much questions,my forum searches were unsuccessful unfortunately.
Nylon I think. The outer part (bg65 anyway) is a Nylon Polymer. The inner core is a nylon multifilament.
Ok I just strung a racket with bg65 at 31/33(32) no pre stretch and it came out at 1267hz left it for 4 days untouched, Final reading was 1209hz. So thats 58hz drop. Another Racket 27/29(28) bg65 1205hz fresh. So [MENTION=1]kwun[/MENTION] I get exactly the same almost 4 lbs loss if you go by Hz in one sense. Only problem is does 59hz = 4lbs now(14.75hz per lb)? the 1205hz on the 28lbs dropped to 1111hz after 7days and about 5hrs on it. 94hz drop/14.75 does this mean it has dropped over 6lbs? because it feels way stiffer than 22lbs. What does everyone think?
Something is a little wonky somewhere with your first stringing I'm thinking ... ime, 1 lb is around 30 Hz give or take a few Hz.
Interesting you should say. Because I recorder after 24 hours aswell. I don't have any answers just can't get my head around it, take a look at this, Using your logic My 32lbs after only 24hrs rest was 1227hz Kwuns 30lbs after 1 day rest 1170hz So about 60hz difference would suggest 2lbs difference and nothing wonky about the job.
