NICE CATCH
The only one on the runway too.
The late night hosts have the same thing for when they are doing their monologues.
Is that the same place he stopped for a good half minute on his way out afterward?
I went back and checked the video before and after the speech.
It looks like on the way out, when he is next to VIPAnon, he stops short of the mark. So a different location.
But still highly plausible that the T is placed there so that he knows where to stop on his way into the arena so that he will be able to see VIPAnon.
