Where the thresholds fall

Every model's representative certification on each rating CEE 2026 checks, with its thresholds drawn. A model must clear every line of one path at once, on one certification, so these single-rating views show each hurdle, not the combined pass rate.
COP at 5°F7,755 rated models · median 1.93At least 86% of rated models reach 1.75 on this rating alone.
