ZM62, 22x23 lbs, 1100 Hz, 3 weeks

Kwun's chart and results suggests approx 26lbs as well, and that's with ZM62 being used.
Were they measured on the same make and string pattern of racquet? Just seems too high. I would expect somewhere around 1140 - 1170 freshly strung looking at others' results.

Of those rackets with zm62 @22x23 lbs in my op, they were strung by stringer A. Iirc at 0h they were around 1180 Hz.

The *stabilized* stringbed frequencies I get do match perfectly with kwun's graph on page 1 for a single string of zm62. Note stabilized after a few days, not immediately off the machine.
So I'd expect Mark's 31 lbs to stabilize around 1300.

Yep - it broke before I even got the chance to play with it. I suspect two things:
1. It was Z62 Mk1 - I was after Mk2,
2. There was a nick in the string - it's happened before, especially with Ashaway.
I don't know how or why it lasted two days, though.

Lol... I think 31lbs has totally exceeded ZM62's elastic limit.

Hmm it seems as if powerhybrid has good tension retention up until you play with it. Dropped all the way down to 1170 hz.
But then again, when I string ZM70 in the low 30's, I really don't see the tension retention everyone talks about as it seems to drop a lot. I guess it's something you have to live with when you string it over 28 lbs?
Makes me want to try thinner strings at lower tensions

I really think rougher strings suffer from this sudden drop in play more than smooth ones do, though, and the Mk1 Z70 was pretty rough.
