How those 67 products graded on our rubric
These are model-based estimates, not laboratory tests, scored on one public rubric. Read the spread against the categories underneath it rather than as a verdict on cast iron in the abstract, because the rubric gives every category a baseline and a term concentrated in one category will carry that category’s spread with it.
Median grade 65 out of 100, across 11 categories.
| Grade | Products | Share |
|---|---|---|
| Excellent | 16 | 23.9% |
| Good | 50 | 74.6% |
| Poor | 1 | 1.5% |
| Bad | 0 | 0% |
