I believe it is safe to say that maintaining absolute platter speed in the presence of an ever changing load (friction from needle tip) is physically impossible!Please explain how the speed of a 22-pound spinning platter can be altered by a stylus whose force is measured in grams.

Belt drives with very long and flexible belts allow more platter movement - idler drive systems with direct coupled idler connection and stiff motor support allow very little angular platter movement with same amount of torque applied to the platter.There's no "angular platter movement" on my belt drive table. It's a VPI.
