feliks,
A better answer would be that the human player is going to be very busy during the match. As long as two mintes sounds, it goes by very quickly. I would recommend that the human player might want to advise the coach of the current score while he/she is feeding the field with tubes. I would not recommend that this person be distracted during a match. Human players when used properly can have a big impact on the strategy of the game. You are after all another set of eyes for your alliance.
