In reply to Roguevfr:
> Scotland haven't played yet, so you'd have to ask the organisers about that. While you're at it,ask them why England have a week between each game?
You could ask them a number of questions, but your own one about England has a certain truth to it, but no solely for England. EG Ireland have exactly the same amount of time off between games as England.
In terms of cumulative days off between pool games the most is 22, the least is 17. Here's a list:
22 - England, Japan, Ireland, France, Italy
21 - USA, Argentina
20 - Wales, Uruguay, Samoa, Tonga
19 - New Zealand
18 - Fiji, South Africa, Georgia, Romania
17 - Australia, Scotland, Namibia, Canada
In terms of most and fewest days off between pool games, this ranges from 4 to 10. More info:
Most (10) - Japan, USA, Tonga, France
Fewest (4) - Australia, Uruguay, South Africa, Japan, USA, New Zealand, Namibia, France, Romania
It averages out at approximately 20 days off per team and therefore is just less than a week per team between pool games with a fair amount of variation.
