You play matches. You run them through analysis engines. You look at your PR. You nod at your
mistakes.
And then you make them again.
Why does this happen? Why do dedicated players get stuck at the same rating for years?
The answer lies in how you study. Passive review—looking at an analysis and saying "ah, yes, I should have hit"—creates a fast-fading memory. Science shows that passive consumption leads to only 10-20% retention after one week.
To break through your plateau, you don't need more analysis. You need Active Training.
Personal Blunder Base (PBB) isn't just another analysis tool. It is a Training Engine that ingests your past match files and converts your specific weakness into a personalized curriculum.
PBB forces you to solve your own mistakes again, without the safety net of seeing the answer first. This triggers Active Recall, a cognitive process that strengthens neural pathways up to 400% more effectively than passive reading.
Load your existing .xg match files directly into the system. PBB scans every move, decision, and cube action from your history.
Get a bird's eye view of your performance. The dashboard breaks down your error rates, giving you immediate insight into where you are bleeding equity.
Don't waste time on trivial errors. Filter your database to find exactly what you need to study—whether it's large blunders (>0.080) or specific types of cube decisions.
Turn those filtered positions into a training pack. Select the number of questions and let the engine generate plausible wrong answers to test your knowledge.
Face your mistakes head-on. The quiz interface presents the position clearly. You must commit to a decision before the answer is revealed.
Review your answer immediately. PBB shows you the correct move and the equity difference, reinforcing the correct pattern in your mind.
Visualize your improvement over time with detailed graphs. Watch your error rate drop as you master the positions that used to confuse you.
Eliminate the specific leaks that cost you close matches. Arrive at the board with the confidence that you've fixed your weaknesses.
Turn volume into value. Your thousands of online matches are a goldmine of data waiting to be mined for improvement.
Coaches can create custom homework (.pbb files) for students. Students can prove their progress with detailed stats reports.
PBB is a lightweight, standalone desktop application optimized for Windows.
Input: Reads standard .xg match files (no external software required to run).
