For a summarized tag, what does a PercentGood value of less than 100 typically indicate?

A PercentGood value of less than 100 for a summarized tag indicates that data errors might exist within the recorded dataset. PercentGood is a metric used to assess the quality of the data; it measures the proportion of good quality data points relative to the total number of data points available.

When this value is below 100, it signals that not all data points meet the expected criteria for quality, possibly due to issues such as corrupted data, missing values, or errors in data collection processes. This is important for analysts and decision-makers as it prompts them to investigate potential discrepancies or gaps in the data, which can affect the reliability of any conclusions drawn from it. In contrast, a value of 100 would indicate that all recorded data points are considered valid and of high quality. Other choices like inactivity of the tag, lack of recorded data, or all data being valid would imply different scenarios that do not align with a PercentGood value less than 100.
