I would imagine that pitch fluctuations caused by stylus drag are less than pitch fluctations caused by 1)variations in motor speed itself, 2) Groove's eccentricities, and 3) record warps causing speed fluctuations as the stylus must effectively move faster over bumps to complete one revolution at 33-1/3.
The last is quite audible if you have an even slightly warped test record that includes a steady pitch (assuming, of course, that the steady pitch was steadfastly done).
Intuition only, does anybody care to do some measurements?
