Results are reported for a refined MFXP CMP for tunings as specified at the September MSE meeting. The primary improvement compared to the previous version of this CMP is achieved by upweighting the contributions of the US_RR indices to the aggregated index used to calculate TACs for the West area. This leads to an improvement in conservation performance for the Western stock for OMs with a future regime shift, without any obvious associated disadvantages. The reason is that these indices detect the effect of such a regime shift earlier than the others available for the West area.
