So after 5 races, the 10 qualified countries would be:

01 FRA
02 SUI
03 GBR
04 ITA
05 ARG
06 AUS
07 NED
08 NZL
09 ARU
10 AUT/DEN (Both are on 31 points!)

This can still evolve of course. No big surprises in this list so far, ARU is really a NED with second passports pissed off at not having be selected by their country…

What's more interesting is who is missing: The country with the Gold in the last olympics on cats is not on this list. ESP, with Iker Martinez and Tara Pacheco, not playing this week due to injury, will need to grab a qualification at another event next year, either the same event (3 spots) or the European Continental Event (1 spot).

Behind, the race is on to try to grab a spot, but it's going to be hard. In current order:

PUR
RUS
GRE
SWE
USA
CAN
ESP
JPN
BRA (will get an automatic qualification as host nation)
VEN
POR
BUL
NOR
BEL
HUN
SIN
MON
HKG
