How to keep tension on last main strings

I have an unrelated question for you Irvin. I've watched your videos starting mains with flying clamps and no starting clamp and you mention you clamp in the dead center of the center mains.

I came across this video and this guy who says to clamp it closer to the throat. Do you think he is mistaken or what are your thoughts? Watch at 6:25 mins.
I like Irvin's way better of putting the clamp right in the middle. Then you are pulling tension on the first 1.5 main and not 1.75 (then the other center main would be tension on 1.25). With the clamp right in the middle you are pulling tension on 1.5 for each and thus they are equal. Also in the video he goes on to do 3 on the same side, but you only need to do 2, then start on the other side. I think Irvin made that second video specifically for me; I have been using that method with great, consistent results.
I doubt that it matters as long as there is enough room to get the clamp between the initial clamp and the frame.
But yeah, it probably doesn't matter too much. But I'd rather the center mains at equal tension.
Also, I don't use the Parnell knot. With the royalty rate now up to $0.03 per knot and me stringing over 3000 racquets/yr, that got to be pretty expensive. Are you paying him by Paypal or just mailing your checks in? Paypal has just been killing me lately with the transaction fees on UK orders.
You mean you're stiffing Richard? No, everyone else here is on board with the compensation strategy devised at the 2015 stringers symposium. It's only fair.

The pro knot, Parnell knot and starting knot are all just knock offs of the Surgeon’s knot if you think about it. But the royalty on the Surgeon’s knot is $300, then you have hospital and anesthesiology expenses to content with too.
I just went through my records and I see the last time Richard invoiced me back on 04/01/17 I made the mistake of selecting the Paypal option. Seriously, be careful on these UK transactions via Paypal. They have really upped the exchange rate fees. It was upwards of $38 on a quarterly invoice. Last I heard Richard was looking at a direct deposit approach. You still get hammered with the exchange rate, but the fees are nominal.
An old timer taught me a knot to tie ( the now called Parnell knot, ) as that old timer taught me to string in 1968. I doubt Richard used that knot back then. The old timer that taught me that knot, said that it would identify my work from others as no one in our area used that knot, and it cinches up easily. He was correct, as only single or double half hitches were used back then in my area.
There was an issue back then, as wooden racquets did not have serial numbers, and a team player on our team told me a knot came undone from my job. Once I looked at it I knew it was not my job, as it was strung with half hitches only. Showed him the knot I used and sure enough he had multiple of same racquets same strings, but a different stringer strung that one.

I think from now on I'll be telling my customers that I use a "jimmy" (jim e) knot. Credit should be given where credit is due, just as jim e gives credit to his mentor, the "old timer".
Besides, it sounds a lot better than a "tennytive" knot.
I did not invent that knot, as it was taught to me from a stringer that taught me to string and he also sold me one of his machines, an old Serrano peddle drop weight machine, (still have that old machine) . It was in 1968 and I was only 13 years old at the time.
That old timer never did give that knot a name, but I bet Richard was the one who brought it to the slam stringers .
That old timer had another machine at that time, that only held the racquet in a vise clamp mechanism when I asked about the tension mechanism missing, he said that he just used a large wooden dowel and wrapped the string around it and hand pulled tension, and used awls to hold tension. Said he strung since he was very young and can pull whatever tension was asked for as he told me there was no tensioning machines back then when he was young.
I remember he had other old machines back then as well, one of them had name of Oliver on it, but he wanted to sell his Serrano, so I ended up with it. That was just over 50 years ago.

Yeah I remember seeing an Oliver with a pedal operated drop weight in a pro shop in western Brisbane - I believe WTA pro Ash Barty used to get her racquets strung on it.
