It does, thanks for replying (and to John above) - not entirely obvious if you're not already familiar with the system though, so you'd think they'd maybe have a link explaining the ranking system. Maybe they do and I'm too thick to see it.
Cheers anyway - at least I know understand how my mate did now.
