Typical of rugby nobody has done a full analysis I can find….but this is helpful:
A recent UEFA study showed football referees made an average of 137 decisions and 60 'non decisions' in a euro tournament. In rugby union we can probably treble the non-decisions. Depending on the level of the match, we can take an average of 12-20 penalties awarded in a match, 15 scrums and lines-out and on paper that's only about 50 or so decisions to make. Simple. But that's not how it works.
A match does not function on only 50 'actual' decisions. With teams between them making about 150-200 tackles per match there's potentially that amount of decisions to make, but we don't see that many because other decisions are being made almost by the second internally by the referee and 'preventative refereeing' kicks in.
