Halcro and Dover are correct although both muddy the waters slightly.
Halcro, by explaining the principles of structural forces necessary to move a sufficiently large armpod and Dover by mentioning the speed-correction circuitry of a DD turntable.
Neither point is relative to the Timeline and a moving armpod.
A moving armpod will be displayed by the Timeline on a belt-drive turntable and idler both without servo control.
The mistake being made is concluding that the Timeline is measuring rotational speed.
It is not.
The rotational speed is pre-dialled into its algorithm so that the flashing strobe merely confirms any deviations.
The Timeline device actually measures 'movement' to a microscopic degree. That is why it is able to visually display the effects of stylus drag as 'movement'.
As Dover points out, in a closed-loop system, any movement of the dependent particles in relation to another will be displayed by a device designed to detect movement.
