EBU Single Rulebook Q&A 13 November 2015 2015_2468 Notification of model changes

Does an alignment of the quantification of default to the default frequency based on an approved method (i.e. an update to the PD scale to better mirror the default frequency) require a notification? CRR states that all changes require a notification but the Commission Delegated Regulation (EU) No 529/2014 does not apply.
