Most of us can hear a quarter-tone difference in pitch, fewer of us can detect an eighth-tone or smaller difference without musical training. New students of violin and guitar, for example may have great difficulty tuning the instrument, especially as the pitch-increments get smaller, but more advanced musicians can easily hear them. This is why trained musicians do not need auto-tuners, they just listen for the correct pitch. I agree with Cafe Latte, small amounts of wow and flutter are clearly audible to me, although may be not to everyone. So regarding the original question, perhaps the threshold of detection for additive amounts of wow and flutter has less to do with theoretical or measured speed fluctuations and more with the individuals ability to hear it.
Its odd but most of the musicians I know don't really give a hoot about the quality of the equipment a piece of music is reproduced over:-from distortion or colouration wow and flutter etc,they are more concerned about how that music is played,in fact a couple of them use equipment most of us wouldn't give house room to
