University Magikarp Campaign Complete History

[ShinPorygon]

“The campaign was publicized in Shogakukan’s magazines for primary-school children in the form of a series of tests in which participants could complete and send back to Shogakukan within a limited period. Those that passed were sent an invitation to a two-day conference in Osaka. On the first day, the participants were separated into three age categories and were then assigned groups based on the various Gyms in the Pokémon games. Each player within one of these groups battled other members of that group, with the top players within each group qualifying for the second day. The second day consisted of a series of battles between the top players within each age category. Those that won a battle during the course of the day were awarded this card at the end of the conference.”

Where does the 2 day battle event in osaka fit into all these? I’m kinda confused here.
