But now then, the current running job (not finished onces, important to say) 
reads the following for the best Gaussian detected :
Power: 1.922769, Fit: 1.326398, Score: -0.15188 (Yes ! A negative number for 
the Score result).

Compare this with my earlier example which was as follows:
Power: 2.306740, Fit 1.337945, Score 2.414156 .

Having a closer look at it, the only thing that puzzles me is the number for 
the Score in the Gaussians (both positive and negative numbers).

Why so ?

Perhaps that negative score has got everyone puzzled...

The Chi-Square Fit should only ever give a positive result, or is there
a version/variation that can give negative scores?...

Or have you found an old bug?!

"Fit" is a measure of how well a rising and falling signal fits an ideal
Gaussian (bell curve) profile. A lower "fit" value means a better fit.
(It's actually a chi-square fit, i.e., a measure of how far the data
departs from an ideal Gaussian.) Since noise can sometimes randomly
simulate a Gaussian, the SETI@Home system only returns a Gaussian
stronger than 3.2 times the average noise level with a fit less than 10.
