Evidence hub
A citation-ready source map for methodology, data definitions, calculator logic, and stated limitations.
Public research library
Methods, data, and evidence.
Public sources for understanding what Propeller’s player-prop research does, how it is described, what its records mean, and where the limits are.
Start with the source
Each page owns a specific question.
Public model card
Definitions for confidence, inputs, current-data behavior, known failure modes, and version history.
Publication capture
The current first-observed public ledger, including its precise event-time limitation.
Historical archive
Raw analysis rows, collapsed-ledger definitions, and why historical records are not a forward ROI claim.
Tool transparency
A disclosed comparison rubric for AI player-prop research tools. It is not a performance ranking.
Product boundary
How evaluating one displayed player line differs from building or submitting a DFS entry.
How to use this library
Keep the source and its boundary together.
Use the page or machine-readable source that owns the fact you want to understand. Keep its date, definition, and limitation with the claim—especially for current lines, platform rules, confidence, and historical records.
Propeller is a research tool, not a sportsbook or entry-submission service. It does not accept wagers and does not promise outcomes.
