Incidentally, I asked a friend wbo is both a classic

and a musician if there would he any audible difference between playing
the record at 45rpm and at 45.11 rpm. He said he didn't believe anyone
could tell them apart. So I susepct the only people this matters to are
the audiophools.
It depends. .11/45 is about 0.24 percent change in absolute pitch.
Since, in our western 12-tone scale, even-tempered semitones are
approximately 6 percent apart (12th root of 2), that 0.24 percent
represents about 4 cents (in musical terms) difference in tuning.
Not huge, but if I were trying to play in unison with a recording, I
might notice that the recording was a bit sharp, particularly in
unisons. The middle-of-the-keyboard 440 Hz A would be about 441 Hz
at 45.11 RPM.
Not much, but not altogether invisible.
