For my Union (seems like not many give a crap about union events anymore), it's the following:

Expert- rank 159, 60 record kills
ultimate- rank 163, 45 record kills
individual- rank 1274, 1,088,756 record PP



also, i said it on another thread, but i think i called it with there being 10k-15k active players (assuming there's some that didn't bother with the event at all)
