Isuzu D-Max 2017: MOT failure rate for its age
22.3% of 23,214 MOT tests of the Isuzu D-Max first registered in 2017 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 96.5 (95% CI 93.9–99.2; 100 = normal for this model at that age): close to other build years of the same model at the same age (within 5 points of normal).

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
