Raw tonnes are not directly comparable across the two dates for that reason; the share-of-pool columns are the fair comparison.","honest_finding":"CORIOLIS's 2010 recommendation ranks the four parties in the same order the real settlement eventually did (EU > Norway > Faroe Islands > Iceland). Its shape changed materially once the platform's 40% dominance cap (R1) shipped: the EU's 2010 claim was 56.5% of the ceiling, which the cap pulls down to 40% -- pushing CORIOLIS's EU recommendation BELOW what was actually negotiated in 2014 (49.4%), a reversal from before the cap existed, when it ran above. The cap is more conservative toward the dominant historical incumbent than the real settlement turned out to be, worth stating plainly rather than only citing the cases where it helped. The capacity the cap frees from the EU cascades to the next-highest-weighted parties: Norway holds steady at 29.2% (uncapped, still +6.7 points above its real 22.5% share), and Iceland's allocation jumps from a near-zero 0.5% to a genuine 17.0% purely as a knock-on effect of the EU's cap, not because Iceland's own weight changed. That lands closer in spirit to what actually happened -- Iceland kept fishing throughout the dispute and the real settlement eventually carved out a shared reserve for it rather than leaving it with nothing -- though 17.0% for Iceland alone still likely runs ahead of what it received in practice: the real reserve (15.6% of a much larger 2014 pool) was split between Iceland, Greenland and other new entrants, not reserved for Iceland alone.","citations":["ICES 2010 advice (619,000t) and 2010 national claims: contemporary fisheries-dispute reporting and analysis of the 'mackerel war', checked this session.","Pre-2008 traditional coastal-states allocation key (EU ~65% / Norway ~35% / Faroe Islands ~3%): fisheries-policy literature on the dispute's origin.","2014-2018 settlement figures (EU 611,205t, Norway 279,000t at 22.5%, Faroe Islands 156,000t at 12.6%, 15.6% coastal-state/NEAFC reserve): contemporary fisheries-trade reporting on the five-year coastal states arrangement."]}
