Those two discrepancies (particularly Canada vs Peace Team) stuck out to me as well.

I think almost everyone who was at the last IC would rate the Canadians fairly highly, definitely a better side than the Peace Team. USA similarly were a good side by international standards, but not better than Ireland.

As Cam pointed out in his example of Denmark vs GB though - if Canada beat the USA in the upcoming test, that could make for a big points jump for them, and a big jump for the USA.

Hopefully as we feed in the results for this year, people can see how quickly things can adjust.

Calculation for up coming USA v Canada match.
As I don't know who the home team is I have calculated as a neutral ground match.
If USA wins their ranking pts. will rise from 44.69 to 45.11 still 3rd.
Canada losing sees their pts drop from 38.92 to 38.49 still 11th.

However if Canada wins their ranking pts will rise to 40.49 putting them into 10th behind Denmark. and USA losing would see their pts drop to 43.11 dropping them back behind Ireland at 6th place.
My placings put
Australia P-1 (P being for professional) (Suggestion)
the other countries are ranked
A-1 and so on (A being for amateur) That gets around fact that Aussie don't play any of the other nations.
