Historic Data Collection is designed to accurately reconstruct past indicator scores based on historical records. Indicators that rely on calculated age values, such as summed age of open problems, cannot be accurately reconstructed because age is a time-relative value that depends on the exact moment of calculation.

Count-based indicators (options A, B, and D) can be recalculated historically by evaluating record states at specific points in time. However, summing age values requires knowing the precise age of each record at each historical interval, which is not reliably reproducible. ServiceNow documentation explicitly warns against using historic data collection for age-based and duration-sum indicators, making option C the correct exclusion.
