This might be stupid but why don't all the orgs attending Sao Paulo use the money riot gives them for partnership to do at least a 2 week bootcamp in brazil, regardless of if they get knocked out or not. Scrimming every day vs the top teams in the world, and at least if every other team goes home after 1 day you're the only one at that level who are scrimming against the teams who are still alive.
Maybe I'm being stupid but that's what I'd do if I ran an org.
