constant monitoring, belt drive turntables play LPs at
different speeds.
My two turntables (an ageing Micro Seiki BL-91 and a
quite recent Rega P9) show perfect pitch, as heard as
well as measured - if a test record with a 1 KHz tone
plays at 1 KHz, taking or leaving minute amounts of wow
and flutter, the speed is 100% correct.
No turntable has precisely the correct speed. Every real-world turntable is
always a little off, one way or the other.
One way to read 100% is 100% +/- 1%. Is that what you mean?
