This question already has an answer here:
What is the formula (I'm not sure it exists at all, maybe it's just a random number) to determine the amount of extra (added) time in futbol (soccer) that get's added after the obligatory 90 minutes.
- I think that it should be the sum of every action that wastes time. Like injuries, corners, etc.
- I almost see, from 1 minute, up to 5 minutes, never more than that.
