What would be interesting would be to see a study of some footy games from different levels with an independent time assessor looking at how much time COULD be added on based on the current LotG versus what is actually added on.
The LotG says:
"Allowance is made by the referee in each half for all time lost in that half through:
• substitutions
• assessment and/or removal of injured players
• wasting time
• disciplinary sanctions
• stoppages for drinks (which should not exceed one minute) or other medical reasons permitted by competition rules
• delays relating to VAR ‘checks’ and ‘reviews’
• any other cause, including any significant delay to a restart (e.g. goal celebrations)"
This gives us lots of scope.
Only one thing is consistent: referees give 0-2 mins 1st half and 3-5 mins 2nd half unless there is something exceptional. We all do it.
But, especially at the end of the match, my guess is we could be giving 10-15 mins if we actually measured every sub properly, every goal, every slow retrieval, every slow goal kick, every injury assessment, every yellow card...
Has this study ever been done?
I might have a go next time I watch a prem game
