I found this interesting, particularly that the hook setup biases against side to side motion vs front to back motion whereas the push nut configuration on my EM (eg. http://www.pbresource.com/images/tilt.jpg) treats movement on any axis the same and doesn't settle into a regular swing.
This video is also shared in another thread: https://pinside.com/pinball/forum/topic/tilt-calibration-guide Is it worth having two? Can they be merged?
