I don't know why having a list, two, or three ready to turn in at a tournament is such a baffling idea.
Why is creating a list on the fly when you get there such a baffling idea? I mean why should someone be forced to do things a given way when there's no harm done in the way they do it?
Now if you have people coming to an event and waiting until they see everyone else's list first you have a problem. If someone isn't ready until 20 minutes after the event was supposed to start then again you have a problem.
But if those aren't happening what harm is there? Again, this thread wasn't even about having a list to give the TO, it was about having a list to give to the other players.
