Referee here,, but I come in peace. There was an interesting article on World cup stoppage time last week. https://fivethirtyeight.com/features/world-cup-stoppage-time-is-wildly-inaccurate/ But what, as coaches, do you expect when it comes to stoppage time? I could ask 10 fellow referees and get 15 answers. But when do you expect us to stop the watch?
What I think is that licensed officials do a great job. I don't remember ever being concerned about a time decision or been critical of one. My experience was that in most youth matches time is not added because of tight scheduling.
Youth matches-it’s irrelevant. Maybe add a minute to each half unless there’s a major stoppage. I was timing the late match yesterday and I clocked about 7 minutes of when the ball was out of play in the first half. Ref only added 4 minutes.
i don't care about adding time back for routine subs, goals, etc., but if a team is deliberately wasting time to kill the game by cycling subs, faking cramps, or whatever, then add more as appropriate. there's nothing more infuriating as a coach than having your team trying to score to win or tie the game, and the other team doing all they can to ruin it. if you're going to add time, it's important to communicate how much is being added so the teams know. also, if it's a blowout, don't add anything.
I usually don't add time unless an injury has really taken away some valuable play time. Never if one or both teams can't seem to keep the ball in play (deliberately kicking it out constantly) because coaches should teach their players otherwise. Like stphnsn stated too -- blow-outs
