One thing I have noticed is that when I have 25 autofollow I have the leader and then one guy on each computer (the active screen) is ahead of the crowd. Like on computer 1, the character on computer 1 is between the leader and the crowd, on computer 2 the active toon (I play in FS) on computer 2 shows on computer 2 between the leader and crowd (i.e. is updated sooner), and 3 shows the active character on computer 3 as the fast one.

So I guess each instance of wow updates where its own character is faster then every other character, duh well ok lol ...

So ya latency, and video update lag is kinda real. Equal to like 5 feet during autofollow.
