FWIW... Once you get to the gate all you see are a bunch of names (tv screen). When I list on Skynet I see where I am with all the codes, but unless I print off the list each and every time I have absolutely no clue who all the other people are once at the gate. So I wouldn't have any idea if I was going ahead of someone I shouldn't be.

The gates used to print off paper with all the standby/PS travelers on it that DID show the codes if I remember correctly, but I haven't seen them do that in a while.

Edit: and of course as I type that the 3 gates near me all put up the piece of paper with names AND codes. Go figure.
