I see much discussion about #superrugby final & the Lions’ altitude/home advantage. I wrote this article years ago: https://t.co/uPkprqV9Zh
Take a team like the Crusaders – they average a 31-14 win at home, and a 23 – 20 win away from home. Best team, historically, in the competition. This means that their home victory margin is 14 points better, on average, than their away margin, which is the size of the home ground advantage to them, in points. In contrast, look at the Stormers of Cape Town. They average a 4-point win at home, and a 1 point loss away, which means that home advantage is worth 5 points. And finally, consider the Lions, the tournament’s historically worst team. They lose by 21 points when away from home, but by “only” 7 points at home. This makes them the weakest home team in the tournament, in absolute terms, but relatively speaking, their home advantage is thus 14 points, similar to the Crusaders. I’ve shown the size of the home advantage for all teams in blue on the right.
