Overtime calculation

[RainDeath]

Hello, I need your help with logic to achieve the desired result. For example, individuals write down the number of hours they work on projects like this: Project A | Ahmet | 9 hours | Wednesday Project B | Ahmet | 3 hours | Wednesday Assuming a person works 9 hours a day as shown above, there is 3 hours of overtime. How can I capture this as overtime in project-based reports? For example, in project B, total overtime hours is 3... Please note that different individuals may record hours on different projects. The total will need to be calculated accordingly.
