Well what I mean is, who is that going to fool? Even an audiophile who is kidding himself that he can hear stuff that isn't there can't deny that an arbitrary speed or the measurement of time don't correlate to sound waves.
It's pretty obvious that if the sine wave is out of synch with the rpm, that there will be deleterious effects on the audio quality.
For example if there were 1.5 sine waves per revolution (say 49.5 sine waves per minute at 33rpm) then the lateral stylus movements caused by the pitch variation would generate additional noise as these movements would not be in synch with the inherent flaws in the platter and mechanism that manifest on each rotation.
