If I'm reading those numbers correctly, perhaps the most interesting conclusion is that the road team is nearly twice as likely to get that killer 5th penalty in a row.
Nah, the bottom row says that if the first 4 penalties are against the home team, the odds the 5th one will be against the home team is very low.
Conversely, if the first 4 penalties are against the away team, the odds the 5th penalty is against the home team is very high. That's the top row.
That's not very surprising, since it's assumed the officials will try and balance out the penalties/not pile on one team. Even though they shouldn't.
But it's the middle columns that are the most interesting (to me). The ones where the penalties are even between home and away after 4 penalty calls. It seems that the 5th call can be determined (a bit) by who took the first penalty of the game. If the home team took the first penalty in an evenly-called game, they have a much lower chance of getting the 5th than if the away team took the first penalty.
Also, for some reason, it's more likely for a penalty sequence to go AHHHH than HAAHH. Might be explained away as the home team imploding after failing to score on their first PP though.
