The general rule of thumb is that it is far easier to
cut an agressive LP than to track it.

Cutting doesn't have to be done in real-time.

Agreed, and there weren't a lot of viable options in the
day of.

Today, we can playback vinyl at any speed that suits our
other needs, and still listen to it with natural pitch
and timbre.

You mean with sample rate conversion? Yes, we could, but
there would be the problem of the delay as the buffer
fills with enough data to go real-time.

Real-time listening is not required.

Unfortunately, slow playback won't help problems due to
bass excursion, and will make the tone arm fundamental
resonance issues more intrusive because they will move
up the musical scale when we listen.

Huh? I would think that all those things WOULD be
mitigated by slowed playback. A resonance at 30 kHz is
better than one at 15 kHz (e.g.)!

Tone arm fundamental resonances are in the 6-12 Hz range. Play a LP at half
speed and bring up to playback pitch, and they are now in the 12-24 Hz
range. Remember, that's the center frequency of the resonance. Tone arm
resonances are moderately damped, so their effects afflict several octaves.
