                [Date.UTC(2000,  9, 27), 0   ],
                [Date.UTC(2000, 10, 10), 0.6 ],
                [Date.UTC(2000, 10, 18), 0.7 ],
                [Date.UTC(2000, 11,  2), 0.8 ],
                [Date.UTC(2000, 11,  9), 0.6 ],
                [Date.UTC(2000, 11, 16), 0.6 ],
                [Date.UTC(2000, 11, 28), 0.67],
