Definition
What this measures
Milestone cohorts connect sustained practice volume to the change in a player’s own rolling performance.
SupaKewber first-party research
Improvement after 100, 500 and 1,000 solves
Milestone cohorts connect sustained practice volume to the change in a player’s own rolling performance.
SUPAKEWBER PRACTICE DATA
Research question
How much do cubers improve after hundreds of recorded solves?
The live dataset will publish a quantified answer automatically after it reaches at least 20 distinct users and 100 eligible observations.
Published results
Aggregate benchmark table
Every displayed cell has passed the public sample threshold. Empty tables are a deliberate “not enough evidence yet,” never a fabricated estimate.

Methodology
How it is calculated
Each user’s first 20 valid solves are compared with the 20 solves ending at milestone 100, 500 or 1,000 within one timer mode.
Inclusion rules
What enters the sample
- Eligible SupaKewber observations with valid measurement fields.
- Only aggregate cells above the stated privacy and stability threshold.
Exclusion rules
What is removed
- Deleted, invalid or structurally inconsistent records.
- Small cells that could be misleading or identify a narrow group.
Interpretation limit
What this dataset cannot prove
This observational comparison cannot prove the number of solves caused the improvement; coaching, hardware and outside practice are unobserved.
SupaKewber data describes people who use this platform; it is not automatically representative of every speedcuber. Definitions and thresholds stay attached to every JSON download so the number cannot be separated from its method.
Source separation
This is practice data, not an official competition result.
SupaKewber records browser practice and platform interactions. Official WCA results appear only on separately labeled WCA analysis pages with the required WCA attribution and export date.
