Ireland top for turnovers, Argentina have worst scrum
Of the eight quarter-finalists, Ireland have won the most turnovers per game (5.3) and average less than 10 penalties per game (9.3) - ranking third.
Their ruck speed slowed from their incredible opening round and is now third-fastest at 3.47 seconds and though their handling and attacking intensity has been superb, their set-piece has slipped and the are ranked sixth for scrum success (90%) and seventh for lineout success (81%).
Their quarter-final rivals New Zealand top a host of the statistical lists on the back of their huge thrashings of Italy and Uruguay, which throws considerable context into their most metres, linebreaks, most defenders beaten fastest overall ruck speed table toppers.
Like Ireland, France's most impressive areas statistically are not their attacking patterns. They have the second-best lineout success (91%), second-best tackle success and conceded the fewest penalties (eight).
They also have the lowest possession time of the quarter-finalists (14:50) and kick the ball away third-most.
Holders South Africa rank surprisingly low on some of their traditionally strong areas. They have the fewest carries per game (108.3) and are in the bottom half for almost everything.
Their scrums had the second-worst success rate and they are fifth for lineout success, though they have made the most lineout steals (2.3).
They are fifth for metres made and defenders beaten, sixth for linebreaks and offloads and, most surprisingly of all, seventh for collision dominance.
They are joint-worst with Fiji in turnovers conceded (17) and four out of 10 possessions end in an error.
Anyone who has had to endure England's four pool games will not be surprised to see that they have had the most kicks in play (33.8) and kicked away possession more than anyone (68%) - the average of the other seven is 54%.
They have the second-fewest carries for the second-fewest metres made, are sixth for defenders beaten and last for offloads.
It is no surprise that Fiji top the chart for the most carries (139.5) and have second-most offloads (11.3) but a sign of their recent development is a surprising position of second-fewest penalties conceded (8.8) behind France.
Traditional fans of Argentina will be horrified to see that they have worst scrum success (80%) and have won fewest turnovers but in attack they have the fastest average ruck speed (3.37 seconds) and the most rucks under two seconds (37%).
In contrast Wales have lost one scrum in four games and top the efficiency charts at 98%.
In a challenging pool, a major factor in their four victories was their red zone conversion rate. Sixth for entries (9.3) and seventh for phases played there, they nevertheless have the second-best scoring efficiency at 3.72 points per visit.
