It depends on the sort of team event, if its one where people co-operate to get a total outcome I agree with you. But in this sort of event there is no co-operative element as its just people grouped together showing individual performance. So even if he performed the best out of everyone, if his teammate did the worst it would literally cancel out his performance due to the team aspect.

Yes thats why no one says its a fact, its a theory

Why would that mean they get to retire earlier then?

Overproduction is how you get blackouts from damaging the grid
