From the new tournament rules:
Taking Notes and Outside Material. Players cannot take notes or reference outside material or information during a tournament round.
OK, so I understand why they don't want access to outside, hidden material. But why can't I take notes during the game?
I've recorded every competitive X-wing game I've played -- it's something I refer to later to help me improve my game play. It isn't blow-by-blow, but quick snapshot of what happens, things to remember for the future, etc. I don't refer to it during the game, but do write between turns while its fresh.
So ... why is that now not allowed?
