Your both fixated on the first two pulls. It's the continuation that is the point. In Irvin's video he first two clamps are correct, but moving the anchor clamp, before doing the second main on the other side (non anchor side) is the wasted movement. It's probably an old habit for you guys or something. I really don't care if I have to spin the frame 180 degrees, you do it all the time stringing. How do tension the whole racket if you don't spin it at least a 180 degrees?
