Unless the motor and table where exactly the same, as well as the drag force of the cutter and sylus the speed in consistancies would occur at different times.
A slow-down on the cutter due to drag would sound "faster" played back with no error, on playback, stylus drag would sound "slower". At first this seems like it would cancel out, but on most tables the inertia would be diferent so it would not occur at the exact same point. Even worse if there is some sort of speed correction that would minutely increase the speed in response to sylus drag at the same time.
Picture the error amplitude as a wave, when two get stacked in the same direction the amplitude is increased.
Is that your point that if every thing was equal otherwise a slow down would become a speed up in playback? That would be really difficult to get right, but in theory you have a point. I think getting the amplitude of error as low as possible is the best we can do, and what most people rightly strive for.
Thanks for making me think about this instead of just making a statement,
