The 3D touch calibration video made me realize just how complicated it is to get the functionality. It's got to be about the worst cost to utilization ration of any feature on the iPhone. Based on my extensive research asking friends and reading various forums.
When the video get taken down, it showed a large device resembling a 3d printer where the phone is precisely mounted while a probe carefully presses on the glass in multiple places to calibrate touch sensitivity. This works in conjunction with a special app running on the attached iMac. The process takes 15 minutes if it works the first time--the instructions indicate that it might fail the first time.
