How to avoid tension loss when tying off Part 3

[Irvin]

In the series of pictures it is hard to see but the mark moved less than the bottom cross I would guess about half the width of the string and I am not sure why. For each of the three knots (one main and two crosses) I wanted to keep out as many variables as I could so I pulled tension with the tension head at 48 pounds. The racket was strung at 57 pounds.

Now for the bottom cross. Same sequence as the top cross except the picture when I released the clamp does not show the drawback well. The camera was out of focus. But the drawback initially was about the same as the top cross very slight. After jumping and banging on the racket the bottom cross moved more. It moved about the width of the string from when the string was marked. That would be 1.22 mm give or take less than my eye can detect.

I hope I have not been too wordy and have explained this well. Sorry for all the threads.

You've obviously gone to a lot of trouble to take pics, so why post them in such a small size?

I put them on shutterfly after I seen they were so small. They are much easier to see in the new thread

Why are you so concerned about tension loss on the tie off strings? Do you like to hit the ball with those strings? Have you ever checked out the tension put on the outside strings in a proportional string job?

Thats fine if you string a proportional stringing pattern but if not, as you say, you do not hit with them, so why not just increase the tension on the end mains, as it does no harm , and it gives a proper tension for them.

As I said in another thread, reasons to increase: (As compared to few reasons not to)
1.It keeps the end mains straighter do to the offset weave of the adjacent main (my most compelling reason)
2.The high end machines all have them (knot button, it ups tension 10%), and they are there for a reason, or the manufactures would not go to the added expense to put it there.
3.I know you do not hit with the end mains, but why not try to keep that string at the closest to the ref. tension as you can.
4.Many customers will pull on that end main, as soon as you give them their racquet back.I have seen that over and over again. When they feel it tight they are happy.A good reason for me as a stringer.
5.I asked the USRSA their stance on this, they said there is no reason to increase the tie offs, BUT there is no harm in increasing as well, so from that statement, it seems they are neutral on this topic.
6.Most tour stringers up the tension of the tie offs, and they have their reasons as well.

There are too many threads on this same subject at same time.
