Hi

I would like to inquire about the functioning of group tickets. On the app or website, it is stated that the Off-Peak Group Ticket is only valid during specific hours. In weekdays until 6:30, from 9:00 to 16:00 and after 18:30. All day on weekends and holidays. The Off-Peak Group Ticket is not valid on King's Day (27 April). It is not allowed to travel with the Off-Peak Group Ticket during rush hour, even if the journey started before rush hours

 To clarify, if we plan to travel at 6:15 AM on a weekday, would the group ticket be valid? My understanding is that the off-peak group ticket during weekdays is only valid until 6:30 AM, so please confirm if this interpretation is accurate?
