The zip tie should be "handshake tight." That means tight enough to stay put on a rotating shaft, but loose enough that the shaft can rotate within it. When the secondaries open, the shaft rotates in a counter-clockwise direction. The zip tie rotates normally along with the shaft, but it is stopped by the throttle screw, so the shaft continues to rotate "inside the zip tie loop." But when the secondaries close, the shaft just rotates back clockwise and the zip tie stays fastened to the shaft in the exact same position. The zip tie will always register the maximum amount that the secondaries opened during a test run.
