Challenge rows appear only after at least 5 saved attempts. User names, emails, project payloads and IP addresses are never included.
The backend recomputes every score from bounded inputs. A browser cannot submit its own pass state, score or PID performance metrics.
The aggregates are available as CSV and JSON under CC BY 4.0. Cite and link to this methodology page when reusing the dataset.
Methodology
Population. Authenticated attempts saved after a learner runs a supported public industrial lab. Anonymous runs are deliberately excluded because they cannot be deduplicated or attached to durable training evidence.
Pass rate. The percentage of attempts meeting the challenge’s fixed acceptance criteria. PID scores are continuous and also require stability and final-error limits; protocol and measurement exercises use explicit checks.
Limitations. This is product-usage data, not a representative survey of every automation learner. Challenge mix, returning learners and curriculum changes can shift the aggregate. Raw personal attempts are not published.
