ciHigh property
CIHigh is the upper bound of that interval. Wilson rather than the normal approximation because the normal one produces bounds past 100 exactly where benchmark scores live — at 194/198 that is the top of the board, not a corner case.
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? ciHigh;
