Sch 11 para 13 Moving weighted averaging process for the annual assessment of achievement of NRVs
For each of the risk categories to which the MWA is applied for carrying out, in each year Y (starting from Y = 2010), the assessment steps described in paragraphs 9 to 12, the following phases must be applied for calculating the MWA Y (a) calculation of the annual observations OBS i returned by the corresponding indicators in paragraph 14 after providing as input the relevant data for the relevant years (the index i takes the values as defined in the formula in sub paragraph (e)); (b) calculation of the 5-year average ( AV ) of annual observation OBS i ; (c) calculation of the absolute value of the difference ABSDIFF i between each annual observation OBS i and the AV . If ABSDIFF i < 0.01 * AV , the ABSDIFF i is attributed a constant value equal to 0.01 * AV ; (d) calculation of the weight W i by taking the inverse of ABSDIFF i ; (e) calculation of the MWA Y as follows— where i is a natural number and x = Y – 6; N = Y – 2.
