2 Yes, it should be a very rare event.
3. This is supported and I can't see how one could read the rules in a way that this is allowed anyway. Line 605 and onward state that "Allowance is made in either period for all time lost..." and I don't think this can interpreted that the referee can cut time. However, we want to investigate the way time loss is compensated in the GameController and document it more clearly for the referees to raise awareness for the time loss they don't need extra compensation for.
5. Ah, that is right, at least the wording of the "kicks from the penalty mark" section will be changed. Since Reinhard wants to touch the FIFA rules as little as possible, I will add a clarifying sentence in Section II saying that this order is fixed unless the ball has not been moved enough so overtime does not apply and that teams can agree to skip regular penalty shoots.
