The two-sigma rule is very rough. Of course, the 100 values of "b" are not independent (although they are identically distributed). To be correct, you need to calculate the correlation between all of them. But as a very rough guide, you can take two sigma. In a more precise calculation, such as in my Fourier-based analysis, you can exactly account for correlations.
