mean property
Mean is the unweighted average of every claim, which answers a different question from Published: what the field says on average, rather than what the vendor says about itself. With one claim the two are equal.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
num? mean;
