So, what statistic do we want to look at? That depends on what you are trying to do with the data. There is no way for Phil to know this, so it is good that he prints out lots of different statistics. That said, when talking about the data quality requirements for structure solution by MAD/SAD, I suggest looking at I/sigma(I) where: I - merged intensity (proportional to photons) assigned to a reciprocal lattice point (hkl index)
Does ANY program print this out...?

sigma(I)   - the error assigned to I

Exactly what I/sigma(I) is required to solve a structure, or make some conclusion about a solved structure is a topic for another day.
