Document-based rating

3.9/10

Low rating (3.5 to 4.9)

Evidence coverage: high

How solid the credit is, as far as the registry's public documents show. Additionality and quantification start from a public grade; permanence starts at 5.0, the neutral point, where none applies, and claim safety always does.
