Why Analysts care about Number Memory
Number Memory tracks digit-span capacity, a proxy for working memory and sequential thinking.
Benchmarks & Interpretation
Compare your number memory scores against cohort averages to spot strengths or risks. Track both best-case and consistency metrics to ensure progress translates into competition.
Lifestyle Levers
Off-game habits move the needle. Start with these levers:
- Caffeine balance
- Meeting context switching
Training Playbook
Run focused BrainGames blocks 3-4 times per week. Pair drills with immediate application—scrims, study, or high-stakes work—to lock in gains.
- Chunking templates
- Spreadsheet recall games
Integration & Review
Review metrics weekly with teammates or coaches. Tag lifestyle variables (sleep, travel, caffeine) so you can correlate them with performance swings.
Action Steps
Practice chunking
Group digits into meaningful clusters.
Use loci
Place chunks inside memory palaces for rapid recall.
Review strategy notes
Track what works so you can double down.

How many sessions per week?
3-4 short sessions are ideal. Stop once accuracy drops below 70%.
Does stress affect span?
