Methodology

Capper Rating is designed to reward sustained, risk-aware performance. It is computed from settled outcomes, not self-reported results.

How CR Works

Every user starts at CR 1000 (Bronze). Each settled pick adds or subtracts a delta from your CR. The delta is based on the pick outcome, the odds, and confidence adjustments.

CR is an additive ledger. Your current CR equals 1000 plus the sum of all deltas from your settled picks. Every change is logged and can be audited.

• 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/lotto exposure reduces delta magnitude
• Additive: CR = 1000 + sum of all ledger entries
• Same formula for all 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, with no edits after posting
• Deletion is blocked by a database trigger, so losing picks stay in the record
• Results are graded automatically from real scores, not self-reported
• One commitment per user per pick, so there is no changing sides
• Settlement is deterministic: same inputs always produce the same outcome

What CR Does Not Do

CR is specifically 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
