For any user, location is decided from the University you are attending, in a team we will look at the majority of individuals to decide the team region, if equal split the team will be by default attributed to the region with the least submission (to increase the chances of that team to be selected).
For example, if 3 people, one from America, one from Europe, one from Asia, and we have the least submission from America, this team will be attributed to the zone ‘America’.
This is the rule we are considering for now but the rule is subject to change depending on the overall number of submissions and we will consider requests from equal split teams to work on a specific time-zone if we deem the request to be justified and fair.
The objective is to have global reach, note that the live final will occur in the time zone you have selected and 4 teams for each region will compete live in their respective time zone.
I hope that clarifies it.
Fairness to all is our main concern. Happy coding ! Lionel.
