in the case of forecast data, the day on which such data was provided.

2.4 Default data

2.4.1 For certain kinds of data set out in Table 1, where data (for a particular period) is not provided to the BMRA for inclusion on the BMRS by the time required under Section Q, default values for such data shall be included on the BMRS as and where so provided in Table 1.
