5.4.3.2.1 General Paragraph four wording is unclear.

This paragraph is understandable, with the exception of the line The StatusCode of the value is still treated as Uncertain when the StatusCode for the result is calculated.

The meaning of this line is unclear, and conflicts with rest of the paragraph. This line should either be removed or clarified.

There is a thought that if there are no good regions, and no bad regions that the status should be Uncertain_DataSubNormal. If this is the case, then the paragraph might be better worded

If all regions in the interval are Uncertain, then the StatusCode should be Uncertain_DataSubNormal. Otherwise, If TreatUncertainAsBad = False then Uncertain regions are included with the Good regions when calculating the above ratios, if the TreatUncertainAsBad = True then the Uncertain regions are included as Bad regions. ~The StatusCode of the value is still treated as Uncertain when the StatusCode for the result is calculated.~ If no Bad regions are in the interval then the StatusCode for the interval is Good. For any intervals containing regions where the StatusCodes are Bad, the total duration of all Bad regions is calculated and divided by the width of the interval. The resulting ratio is multiplied by 100 and compared to the PercentDataBad parameter. The StatusCode for the interval is Bad if the ratio is greater than or equal to the PercentDataBad parameter. For any interval which is not Bad, the total duration of all Good regions is then calculated and divided by the width of the interval. The resulting ratio is multiplied by 100 and compared to the PercentDataGood parameter. The StatusCode for the interval is Good if the ratio is greater than or equal to the PercentDataGood parameter. If for an interval neither ratio applies then that interval is Uncertain_DataSubNormal.
