A feedback loop, not a reverse-engineering contest
Participants should receive weekly automated reports. The purpose is to keep them engaged, reduce confusion, and give them enough signal to debug obvious issues.
The report should stay general. It should say what moved up or down, what looked strong, and what looked weak. It should not reveal exact weights, thresholds, or formulas. The goal is a feedback loop, not a reverse-engineering contest.
Public principles. Private formulas. Enough feedback to debug, not enough to reverse-engineer.
