Yeah, this is a bug - getting Xtriage output to display nicely in the GUI
was non-trivial, and in a few cases I misinterpreted which data arrays were
relevant.  It'll be fixed in the next nightly build.

We agree that it needs to be made much more intuitive - I have tried to
clarify some issues in the GUI but I'm limited to those parts I actually
understand.  Peter and I probably need to spend a couple of weeks revising
and cleaning up the output, but as usual this has to compete with about a
dozen other projects...
