And, I also don't randomly add 10 pounds tension to crosses to compensate which screws up a string job just to make the frame look right. Have you ever played with a frame strung with a 10 pound difference between the mains and crosses? That is totally hosed, and IMO, terrible advice. I'm not being a "know-it-all" when I validly criticize that advice. It's terrible advice, it's not solving the original problem, it ruins the feel of a string job, and it results in a terrible end product for whoever was unlucky enough to pay for that string job.
Let me ask you, if you took your frame to someone to be strung say at 60 pounds, would you want them to add 10 pounds on the crosses to "striaghten it out"? How do you think a string job at 60 on the mains and 70 on the crosses would play? Hell, even 55 on the mains and 65 on the crosses?
Again, I simply cannot believe some of the "advice" that is being handed out. I don't think the issue is a couple of millimeters as much as it is telling someone to 'add 10 pounds' or stretch a frame by applying force to it. And FYI, I've strung plenty of Head frames and never seen any noticeable difference in the head shape after stringing.
Then, live with a shorter frame with a rounder head
You speak like a 10 lb. differential between crosses and mains is unheard of and is potentially frame damaging. People string with 10 lb. cross/main differentials all the time. Personally, if a Head frames slightly deforms post-stringing when pulled off the machine, I don't see it as a big deal. Others may not feel the same. I was giving a recommendation on how to prevent it.

No, it's not. There are people who string 6 pt. mounting on this board who have also noticed certain head frames are rounder and shorter after being pulled from the machine. The issue sounds more like some people don't notice it or measure the frame length after stringing certain Head frames. If one doesn't notice, it's obviously not going to be an issue.
I've never experienced this phenomenon with any frames other than 3 or 4 Head frames (only) and I've strung 500+ frames on my 2-pt stringer. Coincidence? I'm afraid not.
We've all strung these same frames without them compressing.

It would surprise me that the folks at KlipperUSA would tell you to purposely stretch a frame. Not denying, just saying that's not the kind of answers I've received over the years when I've had questions.
I can easily understand how compression could occur with a KM. However, if the frame plates are tightened down with the lip edges securely against the racquet frame at the throat and the head, the racquets don't have any room to move. It must move at the top or the throat for compression to occur, in my mind. Of course, the wing nuts on the upward supports must be secured also. My only disaster, probably 15 years ago, happened when I didn't tighten one of the supports.
Nobody said it happens every type we string one. It occurs when the tension and/or stiffness of the main string overpowers the crosses. It simply pulls the head together longitudinally, making it appear slightly rounder. Once you recognize that, then measure the length and you''ll note, the frame is slightly less than 27" long.
