Did you make this measurement, or were you just told of it?  What was the

1 cent sharp at 440Hz is approximately 440.25Hz
1 cent flat     at 440Hz is approximately 439.75Hz

(1 cent at any freq = 1: 2**(1/1200) = 1.0005777895)

The pitch one gets out of an open A string on a fiddle varies more than 1 cent depending
on how you support the neck of the instrument, how hard you bow the string,
where you bow the string, and what day of the week it is...

Even playing very softly, my violin is drastically louder than my tinitus.
