Grading Outcomes
A graded prop is marked as a win when the analyzed side beats the listed line, a loss when it does not, and a push when the result lands exactly on the line or is otherwise graded neutral.
Canonical Archive Source
The Results page is the canonical explanation. It separates raw graded analysis rows from entries retained after the current public API collapse rules and links each machine-readable source.
Why Totals Change
Totals change as historical rows are added, graded, corrected, or collapsed under current API rules. Always quote the unit and snapshot date, and do not treat either total as a forward-tested ROI record.
Frequently Asked Questions
How does Propeller grade picks?
Propeller grades historical prop outcomes as wins, losses, or pushes after final results are available. The Results page explains the units, sources, and limitations of that archive.
Where can I inspect Propeller results?
Use /results/ for the canonical archive explanation and /track-record/ for grading methodology. Machine-readable sources are linked from /data/index.json.
Do past Propeller results guarantee future performance?
No. The historical archive includes repeated analysis snapshots and legacy retrospective data. It is research context, not a forward-tested ROI claim, and past performance does not guarantee future results.
