What's Changing?

• Standardized High Hit Factors: We've developed a data-driven method using Weibull statistical distribution to calculate consistent, objective HHFs across all divisions.
• Reinstatement of 23- and 24-Series Classifiers: These stages have been recalibrated with proper HHFs and will be reinstated into the active classifier list.
• Classification Algorithm Updates:
  • Removal of B, C, and G flags
  • Modified D flag logic:
    • Same-day scores for the same classifier and division will be averaged (SDA)
    • Different-day scores will use the most recent attempt (MRO)
  • Increased score ceiling from 100% to 110% of HHF
• Classifier List Optimization: Some underperforming classifiers will be retired, maintaining a balanced set of stages that correlate well with Major Match performance.

Why These Changes Matter

• Accuracy: The new system better represents consistent performance rather than isolated peak moments
• Objectivity: HHFs are now calculated using a standardized method without subjective adjustments
• Fairness: The system provides equitable measurement across divisions while accounting for recent rule changes
• Correlation: Classification percentages will better align with actual Major Match performance

What This Means For You

• Your current classification letter will not be downgraded
• Classification brackets remain unchanged (95% GM, 85% M, etc.)
• Most shooters will see a slight increase in classification percentage
• The system will better reward consistent performance rather than "Hero-or-Zero" approaches

Implementation Timeline

These changes will take effect on April 2nd, 2025.
