What is MO3?
MO3 stands for "Mean of Three," which refers to the average time of three consecutive solves in speedcubing. It is a widely used metric for evaluating a solver's performance, particularly in informal settings or practice sessions. Unlike a single solve time, MO3 provides a more reliable indicator of consistency and skill level.
Key Features of MO3
MO3 is favored by many cubers because it eliminates the influence of outliers—either exceptionally fast or slow solves—that might skew the results. By focusing on three consecutive solves, it offers a balanced view of a solver's abilities. Additionally, MO3 is easy to calculate and track, making it accessible for both beginners and advanced cubers.
- Simple to compute
- Reflects consistency
- Eliminates outlier influence
Why is MO3 Important?
In speedcubing, consistency is key. While single solve times can be impressive, they don't always reflect a solver's true skill level. MO3 addresses this issue by providing a more accurate representation of a solver's performance over multiple attempts. This metric is especially valuable for tracking progress and setting realistic goals.
Benefits of Using MO3
Here are some reasons why MO3 is crucial for speedcubers:
- Consistency Check: MO3 helps identify patterns in your solving style and highlights areas for improvement.
- Progress Tracking: By regularly calculating MO3, you can monitor your progress over time and celebrate milestones.
- Goal Setting: Setting MO3 targets can motivate you to practice more effectively and push your limits.
How to Calculate MO3
Calculating MO3 is straightforward. Simply solve the Rubik's Cube three times in a row, record each solve time, and find the average. The formula is:
MO3 = (Time1 + Time2 + Time3) / 3

Example of MO3 Calculation
Let's say your three consecutive solve times are 15.2 seconds, 14.8 seconds, and 15.5 seconds. To calculate your MO3:
MO3 = (15.2 + 14.8 + 15.5) / 3 = 15.17 seconds
Your MO3 for this session would be approximately 15.17 seconds.
MO3 vs. Average
While MO3 and average might seem similar, they serve different purposes in speedcubing. MO3 focuses on a small sample size (three solves), making it ideal for quick assessments and practice sessions. On the other hand, average calculations typically involve larger sample sizes, such as five or twelve solves, providing a broader view of performance.
When to Use MO3 Over Average
- During short practice sessions
- For quick consistency checks
- When preparing for competitions
Common Mistakes When Using MO3
Even though MO3 is a straightforward metric, cubers sometimes make errors when calculating or interpreting it. Here are a few common mistakes to avoid:
- Ignoring Outliers: While MO3 reduces the impact of outliers, it doesn't eliminate them entirely. Be cautious of exceptionally slow or fast solves that might affect your results.
- Not Practicing Consistently: MO3 requires consistent practice to yield accurate results. Skipping sessions or practicing sporadically can lead to unreliable data.
- Overemphasis on MO3: While MO3 is important, it shouldn't be the sole focus of your practice. Balancing MO3 with other metrics like single solve times and averages is essential for overall improvement.
Improving Your MO3
Improving your MO3 involves a combination of practice, technique refinement, and mental preparation. Here are some strategies to help you enhance your MO3:
Tips for Better MO3
- Practice Regularly: Consistent practice is the foundation of improvement. Set aside time each day to work on your solves.
- Refine Your Technique: Focus on optimizing your algorithms and finger tricks to reduce solve times.
- Stay Calm Under Pressure: Mental preparation is crucial, especially during competitions. Practice staying calm and focused during timed solves.
Long-Term MO3 Strategies
For sustained improvement, it's essential to adopt long-term strategies that align with your goals. Consider the following approaches:
Building a Practice Routine
Develop a structured practice routine that includes:
- Warm-up sessions
- Algorithm practice
- MO3 tracking
Setting Realistic Goals
Set achievable MO3 goals and track your progress regularly. Celebrate small victories to stay motivated.
Competitive MO3 in Speedcubing
In competitive speedcubing, MO3 plays a significant role in determining rankings and qualifications. Many competitions use MO3 as a criterion for advancement to higher levels. Understanding how MO3 is applied in competitions can help you prepare more effectively.
MO3 in Official Competitions
According to the World Cube Association (WCA), MO3 is often used in unofficial rankings and practice sessions. However, official competitions typically rely on larger sample sizes, such as average of five or twelve solves, to ensure fairness and accuracy.
Tools for Tracking MO3
Several tools and apps are available to help you track and analyze your MO3. These tools provide valuable insights into your performance and offer features like graphing, statistics, and progress tracking.
Popular MO3 Tracking Tools
- Cubing Timer Apps
- Online Solver Platforms
- Spreadsheet Templates
Conclusion
MO3 is an indispensable metric for speedcubers, offering a reliable way to evaluate consistency and performance. By understanding how MO3 works and implementing strategies to improve it, you can enhance your cube-solving skills and achieve better results. Remember to practice regularly, set realistic goals, and utilize available tools to track your progress.
