I am an academic quantitative researcher who primarily teaches statistics and quantitative methodology (not in Statistics, though).  Even with frequent use of the ignore option here, the signal/noise ratio is too low lately.  However, it is like mining low grade ore.  The nuggets you find after time are well worth it.

 

Nebbya great reference to signal/noise ratio.  If I may ask, are you in the electronics industry, or an audiophile, or etc?  I have a varied technical background, including some electronics.    -bbq
