I think that one of the following things occurred:
1) argos meant for the finals to be completed after 2 successful kills [just like earlier rounds] - which seems to be the case since he named me champion
2) argos sent game 3 PMs to all the other participants and people didn't join in time [I did manage to get in]
3) argos had something come up and realized he wouldn't have time to complete the tournament and therefore used the existing results with me having a considerable lead
It could be a combination of these.
