No championship gets an asterisk. Just a different TDI score.

SRS is a regular-season rating based on scoring margin and strength of schedule. Zero is league average. Each series has equal weight. Map each opponent to the ladder, adjust for eligible availability once, then average. Higher points mean stronger opponents.

Exact cutoffs enter the higher band. Opponent availability is not deducted again from Matchup.

Opponent rates: leading player 22/3; other core 11/3. Multiply by unavailable game equivalents ÷ series games. Sum within a series, cap at 110/9 and raw Strength, subtract, then average series.

NBA eligibility: exactly two leading players plus established other core players, including one primary sixth player. A player must appear in at least half the team’s regular-season games while on the roster. Partial loss uses documented unavailable regulation seconds ÷ 2,880, not ordinary bench minutes.

Subtract the champion’s regular-season SRS from each opponent’s SRS. Round that difference to two decimals before lookup. Map to the ladder and average equally across the actual series. Higher points mean the champion was more outmatched; this is not a betting probability.

Required victories: 1–3 → 3 points; 4–6 → 6; 7–9 → 9; 10–12 → 12; 13+ → 15.

Count required victories, not games played. A bye adds no phantom opponent.

Disadvantaged series: 0 → 0; 1 → 1.5; 2 → 3; 3 → 4; 4 → 5. Use scheduled home allocation and deciding-game venue, not simply who hosts Game 1.

Series extension /7 = 7 × losses ÷ (wins needed − 1), averaged equally across series. An undefeated qualification pool earns zero extension.

Elimination survival /3 = 0.5 per win while one loss from elimination, capped at 3 for the run.

Player credit = role rate × unavailable game equivalents ÷ actual games in the series. Champion rates: leading player 3; other core 1.5. Sum within the series, cap at 5, then average series.

NBA eligibility: exactly two leading players plus established other core players, including one primary sixth player. A player must appear in at least half the team’s regular-season games while on the roster. Partial loss uses documented unavailable regulation seconds ÷ 2,880, not ordinary bench minutes.

Playing hurt does not receive an assumed effectiveness penalty. Documented medical unavailability and qualifying external suspensions count; healthy benching does not. Ranges preserve unresolved exposure.

At least three current core players must have appeared for the franchise in each credited prior season.

0.5 for reaching the format-relevant semifinal/conference-final stage in both prior seasons; otherwise 0.

WNBA eligibility: exactly two leading players plus established other core players, including one primary sixth player. A player must appear in at least half the team’s regular-season games while on the roster. Partial loss uses documented unavailable regulation seconds ÷ 2,400, not ordinary bench minutes.

Single-game stages count in availability averaging. National-team commitments are not medical absences.

Subtract the champion’s regular-season SRS from each opponent’s SRS. Round that difference to two decimals before lookup. Map to the ladder and average equally across the actual series. Higher points mean the champion was more outmatched; this is not a betting probability.

15 × required victories ÷ longest available route that season. Longest route: 1997 = 2; 1998 = 4; 1999 = 5; 2000–04 = 6; 2005–15 = 7; 2016–24 = 8; 2025 = 9. Byes add no stages.

Disadvantaged stages: 0 → 0; 1 → 1.5; 2 → 3; 3 → 4; 4+ → 5. Use scheduled home allocation and deciding-game venue. Away single-game knockouts count; neutral or balanced stages do not.

7 × losses ÷ (wins required − 1), averaged over eligible multi-game series. Single-game stages are excluded. With no multi-game series, extension is zero.

0.5 per win when one loss from elimination, capped at 3. Single-game knockout wins qualify.

The category ceilings add to 105: 100 base points plus 5 Context points. This is an arithmetic ceiling, not a claim that one real championship can satisfy every maximum simultaneously. TDI is not a percentage.

No assumed loss-of-effectiveness penalty is assigned to a player who plays hurt. Documented medical unavailability and qualifying external suspensions are evaluated under the eligibility rules. Healthy benching is not a medical absence.

NFL availability compares postseason medical availability with the player’s regular-season participation baseline. Better postseason availability can produce a negative contribution. A negative opponent adjustment can increase opponent strength, subject to its cap.

A range preserves unresolved eligible exposure rather than inventing a precise value. It is a supported scoring interval, not a statistical confidence interval. The midpoint is a display summary, not the most likely outcome.

Ranks use exact lower bounds; headlines use rounded midpoints. Different ranges can therefore produce headline scores that do not follow rank order. Overlapping ranges do not establish a definitive ordering.

Quarter points make headline scores easier to read. Factor details retain two decimal places to explain the calculation. Displayed components can differ slightly from the total because they are rounded independently. Exact values remain available in the dropdown and table.

They capture game volume, consecutive late-stage finishes and the immediately preceding championship. Their overlap is intentional and their weights are limited to 2, 0.5 and 0.5 points. They should not be interpreted as independent proof of fatigue, pressure or reputation.

Opponent Strength measures the opponent’s rating. Matchup Disadvantage measures the gap between the opponent and champion. A strong opponent can still be weaker than an exceptional champion. The overlap in team-rating inputs is intentional; opponent availability is adjusted once in Strength.

No. Confidence and controversy badges have been removed. Evidence limitations remain in score notes, missing-data labels and supported ranges. Missing historical evidence does not automatically mean no injury occurred.

The explorer lets you sort published points across leagues, but it is not an official combined ranking. League-specific ladders and formats differ. Every official rank and movement arrow remains within its own league.

The leagues use adapted scoring rules and different score distributions. NBA thresholds are 60, 67, 74, 77 and 85. WNBA and NFL thresholds are 60, 65, 70, 75 and 85. All three label totals below 60 Below Moderate, and all include Context.

Expand a card for the narrative, exact total, range, factors, minibars and subfactors. Tap an information button for the rule. Switch to Table to compare factors, choose lower or upper bounds for sorting, and export the currently filtered table. Exported factor values use the selected bound.

The current score uses five base factors and Context. Historical Pressure Index, Signature Achievement Bonus and separate Finals or Super Bowl bonuses are not additional scoring categories. Era labels remain descriptive; they do not add an extra score.

The approved workbooks retain historical gaps. Some NFL entries preserve approved path-level inputs without a full original game-metric ledger. The WNBA workbook does not supply all opponent names or series results. Notes distinguish missing details from known zeros. New evidence can lead to revisions.
