EBU Single Rulebook Q&A 28 March 2019 2019_4638 Wide usage portability between Member States

Could three months’ data, showing wide usage of the dedicated interface, produced in one Member State by a regulated entity (ASPSP) belonging to an ASPSP Group, be used as evidence to support the ‘widely used’ condition in a further Member State for a separate regulated entity (ASPSP) belonging to the same ASPSP Group, on the condition that both entities employ the same dedicated interface?
