Methodology
How the ranked ladder is computed.
Capper Rating uses an additive ledger keyed on (user, pick, source). Every settled pick writes a delta you can audit; a tracked X handle's posted picks are graded with the same formula as any user's commitments, so a source can't be ranked on a different scale than the people tailing it.
One write per pick per source
Every pick is keyed on (user_id, pick_id, source_type). Duplicate writes are silently dropped, so a tracked source cannot game CR by re-emitting picks.
Additive and auditable
Every delta is written to an immutable ledger. Current CR is the baseline plus those recorded deltas.
Manipulation resistant
Capper Rating cannot be bought. Database triggers block deletes at the row level; losing picks stay on the record.
How CR works
Every user starts at CR 1000. Each settled pick adds or subtracts a delta from your CR based on the outcome, the odds, and confidence adjustments. CR is an additive ledger: your current CR equals 1000 plus the sum of all deltas. Every change is logged in an immutable audit trail.
- Profit-weighted.Wins at longer odds produce larger positive deltas.
- Confidence-dampened.Small sample sizes are penalized until 20+ settled picks.
- Variance-penalized.Heavy parlay exposure reduces delta magnitude.
- Additive and immutable.CR = 1000 + sum of all ledger entries.
- Source-agnostic.Same formula for real users and tracked sources.
Pick integrity
Rankings are only as trustworthy as the picks behind them. Slipstream enforces integrity at the database level, not in application code.
- Picks are locked before the event starts. No edits after posting.
- Deletion is blocked by a database trigger. Losing picks stay on the record.
- Results are graded automatically from real scores. Never self-reported.
- One commitment per user per pick. No changing sides after the fact.
- Settlement is deterministic: same inputs always produce the same outcome.
The rank ladder
Seven base tiers from Bronze to Grandmaster. Bronze through Master each have four Roman-numeral divisions. Grandmaster starts at 2,500 CR and has no division. Tier is provisional until 20 picks settle.

What moves your CR
- ROI% as the primary signal
- 7-day rolling performance, weighted for recency
- 30-day stability anchor against variance

What CR does not do
CR is designed to resist manipulation.
- CR cannot be purchased. No pay-to-rank mechanism exists.
- CR does not factor in follower count, activity volume, or engagement.
- CR does not use self-reported results. Only automated settlement counts.
- CR does not reward deletion. Deletes are blocked at the database level.
- Tracked sources are graded by the same formula as real users.
