Most data will have channels for Iref, the beam intensity from a reference sample. This is often much cleaner than the actual sample, and can help determine the edge energy and whether there has been beam drift.
It might also be convenient to plot the edge energy as a straight line on the output graphs (or at least the "fitting" graph) as it would help in cases like #47 to see if that's the cause of poor fits.
