In Scotland, we dont program the board anymore.
The sole focus is assisting the referee with stuff he cant see, the tech areas is a secondary concern, if they causing you that much of a problem that they are affecting your ability to assist the referee (putting you off your game) then they need removed.
Priorities. A sub board. Or the red card punch/head butt that we missed
The sub can wait. We simply have to get the correct calls on the park, esp with four officials. 8 eyes cannot be excused for looking elsewhere in the clip in question.
Don't disagree, but there will still be times that the 4th official isn't looking at play. He may be speaking to someone to calm them down, he might be speaking to the floor manager (I speak from experience that this happens a lot in each game), he might be speaking to the stadium safety manager, plus in England even at the top level the 4th man does program the board.
