USA needs a top three placing at Pan Ams to qualify for the Olympics. However, with Canada already qualified, USA can actually be top 4 and still qualifiy should Canada place ahead of them.
Actually both Canada and Brazil qualified at WEG, so we only need to be top 3 not counting CAN and BRA. If we don't manage that, but Mexico does, then we get the sole individual slot allocated to North America. If neither USA or MEX gets a team in, but Mexico has a higher placed individual at Pan Ams, then they get the individual place and we don't go at all.
