I made another video hopefully with better sound: https://photos.app.goo.gl/nESH5um2LB7S11LN6

Since the sound is more pronounced when (or maybe even not present until) the vario cam actuators activate, perhaps unhooking them as Homeoboxster suggests would add a clue if the noise goes away? (the additional tension of actuation is required to cause it)

Coming full circle to what I know I have to deal with anyway could it be that part of the pad broke away and the noise is the chain hitting/rubbing part of the metal support as it is actuated and the angle changes, but when it is not actuated it is riding on what is left of the pad?
