Another possibility is that TRN is showing their current residency, which may not be the same residency they had when they played in that event. I have noticed that when a player moves and changes sections, when you go back and look at the results it shows the current section for the player rather than the section they were a resident of a the time they played the event.
Yep, thats what I was going to say but it disappeared from my brain when I started typing.... And now that you say it, I remember what I wanted to say.... I hate when that happens.
