Teams can receive up to 5 passes. It is based on the number they register.
5 examples:
1. If a team has 4 members and one of the members is their slammaster, they receive 4 passes.
2. If a team has 4 members and a slammaster, they can receive 5 passes.
3. If a team has 5 members and a slammaster, they receive 5 passes and must purchase a pass for the 6th person.
4. If a team has 4 members, a slammaster, and a coach, they receive 5 passes and they must purchase a pass for the 6th person.
5. If a team has 5 members, a slammaster, and a coach, they receive 5 passes and they must purchase a pass for the 6th and 7th person.
I don't think there is a rule that states the coach must be a PSi member, however they will be required to sign the code of honour if they are acting in an official capacity during the event.
