This PR aims to enhance the accuracy of the average review time calculation by excluding self-reviews, which aligns with our goal of improving code quality and user experience. This change is similar to previous decisions made regarding the removal of dead code in the calculateStreak function, which also focused on ensuring accurate functionality. Thank you for your contribution, and I look forward to your updates!
