The point is, in this group there's one team that's surely stronger (Korea) and one that is at least at the level of France, Sweden, China, UK, US and Canada, and Russia barely lost to Finnland.
Now imagine the Los Angeles group wit Russia instead of Canada: US might beat them, but might also lose to Russia, in any case they would be probably second at worst.
Immagine the Paris group Russia instead of the UK, same as above France could both win and lose to Russia, and again they could be second.
Same story for the Bangkok group, Russia instead of Sweden...
There's no way around it, this was the hardest group of them all, and after the Korea Vs Finnland match I'd also add, by far.
