Tactical improvement is about pattern recognition. Disco Chess tracks three metrics that directly measure this skill, plus weakness analysis to guide your training.

The Three Core Metrics

Every puzzle you solve contributes to three metrics. Together, they answer the question: Are the patterns becoming automatic?

Accuracy

The percentage of puzzles you solve correctly on your first attempt. This measures your ability to recognize patterns and calculate accurately.

What to aim for:

60-75% in Cycle 1: puzzles are at the right difficulty
75-85% in Cycles 2-3: patterns are starting to stick
85-95% in Cycles 5+: approaching mastery

If accuracy isn't improving: The puzzle set may be too hard. Drop to an easier set where you can maintain 70%+ accuracy. Building a strong foundation matters more than struggling with difficult puzzles.

Solve Time

How quickly you solve each puzzle, measured in seconds. As patterns become automatic through repetition, your solve time naturally decreases. This measures pattern recognition speed, critical for time-pressure situations.

Goal:

Maintain accuracy while speed increases. If you're solving faster but accuracy drops, you're rushing. If accuracy is high but times aren't improving, the patterns aren't becoming automatic yet.

If times aren't decreasing: You might need longer breaks between cycles (1-3 days is optimal). Back-to-back cycles turn into memorization, not learning.

Efficiency

Combines accuracy and speed into a single number showing your overall improvement compared to your first cycle. Calculated as:

Efficiency = (Accuracy ÷ Avg Time) ÷ (Cycle 1 Baseline)

Benchmarks:

1.0x (Cycle 1): your baseline
1.5x (Cycles 3-4): solid improvement, patterns starting to stick
2.0x (Cycles 5-6): excellent progress, most patterns internalized
2.5x+ (Cycle 7+): mastery, patterns are fully automatic

Weakness Analysis

Beyond cycle metrics, Disco Chess analyzes your solving history to identify tactical patterns you struggle with.

Tactical Profile

Your dashboard shows a radar chart of accuracy across all 18 tactical themes. At a glance, you can see which motifs are strong (high accuracy) and which need work (low accuracy).

For example, if your fork accuracy is 89% but your pin accuracy is 58%, you know exactly what to train next.

Personalized Recommendations

Based on your weakness analysis, Disco Chess recommends specific theme-based puzzle sets to target your weak spots. Click through to jump directly into focused training.

Why Not Puzzle Ratings?

Traditional puzzle platforms assign you an Elo-style puzzle rating. While this feels satisfying, it's counterproductive for learning:

Ratings encourage cherry-picking: you avoid hard puzzles to protect your score
Ratings penalize repetition: solving the same puzzle "inflates" your rating, even though repetition is how you actually learn
Ratings create anxiety: daily fluctuations don't reflect actual skill changes

Disco Chess focuses on pattern mastery instead. Our metrics answer what matters: Are you recognizing patterns faster and more accurately?

How Analytics Translate to Real Games

The goal isn't to get better at puzzles. It's to improve your real-game performance.

High accuracy (80%+): You'll spot tactical opportunities your opponents miss. You'll win more material and convert advantages more reliably.
Fast solve times: In time pressure, automatic pattern recognition keeps you from blundering. You'll make better moves faster.
High efficiency (2x+): You've achieved pattern mastery. Tactics will "jump off the board" at you without conscious calculation.
