What was the order of discrepancies and duplicates? Single cases or mass?

The order of discrepancies and duplicates depends on the context of the task, but generally two scenarios can be distinguished:

• Single cases. When discrepancies or duplicates are rare, it may be related to input errors, rare bugs, or exceptions in logic.

• Mass cases. If there are many duplicates or discrepancies, it indicates a systemic problem — for example, insufficient data validation, errors in processing algorithms, or issues with data sources.

To assess the situation, it is important to analyze logs and statistics to understand the scale and causes. For example, if 5% of game objects in the database are duplicates, this is already a serious reason for refactoring and process improvement.
