If everything in the real world could be explained through physics and theorems and stuff, we would all be visor than we are...

Lol! Lemme check the coefficient for cobalt and see if I need to subject it to extreme temps...

2 rackets. NS9000, AT900P
both strung with NBG98 @ 23.8/26lbs

VS850 at 24 lb on SW30 from 9 months ago, rarely played
1027 Hz at 20C
1023 Hz at 5C
1027 Hz at 20C again
So, there is a trend. Tensions fall off a tad when colder. But this is only like 0.1 lb and the string material hardening with colder temp is probably more significant in causing a harder brittle feel in the cold.
Still would be interesting to see what happens in Asia going from 20C to 35C. Anyone?

Looking at a few frequencies provided and comparing, it seems to me like Victor racquets tend to have a lower frequency at the same tension as lets say Yonex. Could have to do with the fact that they don't fill the racquets with foam.

not quite sure exactly where they put it since I haven't looked at the whole thread and haven't translated what he says. Doesn't seem to be in the whole frame though. Could still have an impact on frequency though, I think.

If anybody hasn't got an iPhone - I can't be the only one - there's a free program called PitchPerfect that does exactly the same thing on a PC. All you need is a microphone of some kind.
Just tested a couple of strings against generated tones, and they sound spot on. Now I've got some kind of objective measure of tension loss, but this means I'm probably going to re-test everything. Thanks, OCD!

Interesting to see how much tension is lost early on... just tested the Adidas Power Tour 66, and it's gone from 1277 Hz to 1228 Hz in 12 hrs before it's even hit a shuttle! 3.8%, IOW.
Looking forward to seeing the "fresh" frequency of Zymax 62 at 30x31...

As a reference, my ZM62 @22x23 lbs ECP :
0hr = 1212 Hz
