Birkhas haChamah is set to 365-1/4 day years, even though we knew tekufas
R' Adda was a more accurate estimate of the solar year. There are
numerous examples of chazal knowingly ignoring scientific accuracy in
facor of commonsensical notions of reality.

CM responds:
I think there is a fundamental difference between accepting a close value as reasonably close enough for practical use (as in your example of tekufas R' Adda, or the values of Pi, or the length of the hypotenuse of a right angled isosceles triangle etc) versus something where the fundamental idea is totally incorrect.
