your math is a little off ...

.. either that or my reading comprehension is, but looks like he's reporting an error of about .33/33.33, which is 1%.

Still, doesn't seem that big a deal, and without knowing the power line frequency at the time, hard to make an assessment about whether it's an issue. The line frequency does vary, it is only specified as an average accuracy. And negative feedback control systems sometimes degrade the sound of audio components as well, so speed stability and accuracy alone may not be enough to determine the best sound. There have always been turntable designers that felt plugging the motor directly into the power line gave the best sound, and designers that felt it best to regenerate the motor drive signals.
