Well, 45.11/45 is 1.00244.. big string of 4s, according to Python.
I can just about hear a one cent difference in tuning (as verified with an
elderly digital synthesizer). 1.002 is one fifth of that, a very tiny
difference indeed. At middle A, it would take you from 440Hz to 440.88Hz - I
can try generating these frequencies later and see if I hear a difference. I
might - mixing them would give a beat period of a little over a second - but
I doubt it, especially in the context of music rather than pure tones.
Probably someone with perfect absolute pitch wouldn't hear it.

I got my math
wrong. The fellow is also wrong.
45/60 = .75.
100/.75 = 133.333....
If rounded to 133, you get 45.11278195----
Incidentally, I asked a friend wbo is both a classic computer enthusiast
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.
