I have a simple question about Tracking:who decide who goes first when two different tokens of opposite sides come at the same time?

I'm playing my first game and sometimes I have the feeling i'm forgetting something...Players often do not suffer fatigue and stress if not for bad actions activation or because they decide to do more manouvres right?

If player and monster tokens are both at same point on initiative tracker (say both at 3) the player side wins tie - that is the rule (sorry don't have page reference handy, it's in the original box set material).

I put player tokens on one side and monster on the other side to keep track of this sequence.
