Hi Aline, I see nothing wrong with <I>/<sigI> being 0.83
Mean((I)/sd(I)) is <I/sigI>, which is not the same as <I>/<sig> so you cannot expect the numerical values to be the same (even in case the resolution shell definition is identical), although the two values usually do not differ much. Take for example two reflections, I1=100 sigI1=20 and I2=200 sigI2=10. Then <I/sigI>=(5+20)/2=12.5 and <I>/<sigI>=150/15=10 .
