Why this rating?

The published Racquet Rating is the sum of five weighted model components. This is that sum, for Marin Cilic.

Racquet Rating 541.0. Five model components, largest contribution first: Performance Index, 206.6 points; Form Momentum, 150.5 points; Surface Balance, 75.7 points; Era Normalization, 61.5 points; Match Context, 46.8 points. Together they total 541.0 points, which reconciles with the published rating of 541.0. Component scores are 0 to 100; contributions are rating points out of 1000.

The largest contribution is Performance Index, at 206.6 of the 541.0 rating points (38%), followed by Form Momentum at 150.5 (28%). Match Context contributes least, at 46.8 (9%). The rating is computed from 85 qualifying matches over the 4-year rating window.

  1. Performance IndexLargest contribution

    206.6rating points38%

    Score 59.0 out of 100 × weight 35% × 10 = 206.6 rating points

    What Performance Index measures

    How well the player wins points and matches — serve and return points won, break points converted and saved, results against elite opponents, and the strength of the field they have faced.

    It carries the most weight of any component, so it usually accounts for the largest share of a rating.

    Seven inputs are winsorised, standardised against fixed baselines and combined through a logistic map to a 0–100 score. Elo and strength of schedule are two of those seven inputs — they feed this component, they are not components themselves.

    Across the 159 rated players this component contributes between 76 and 328 rating points — a spread of 252.

    These are the observations the component was computed from. A higher share with the full feature set means more of the serve, return and break-point detail was available.

  2. Form Momentum

    150.5rating points28%

    Score 60.2 out of 100 × weight 25% × 10 = 150.5 rating points

    What Form Momentum measures

    Recent trajectory: results over a 26-week window with exponential decay, a fatigue adjustment from minutes and sets played, and an allowance for a player returning after a long absence.

    It is what makes the rating a current-form measure rather than a career résumé.

    The published score is shrunk toward the neutral 50 in proportion to how much evidence supports it, so a short hot streak is damped rather than treated as equal to a long validated record. Both the raw score and the confidence used are published, so the adjustment can be checked.

    Across the 159 rated players this component contributes between 81 and 219 rating points — a spread of 138.

    The published score is 50 + (raw − 50) × confidence. Confidence rises with matches, span, distinct opponents and top-opponent exposure, so a short run is damped toward neutral rather than treated as a settled trajectory.

  3. Surface Balance

    75.7rating points14%

    Score 50.4 out of 100 × weight 15% × 10 = 75.7 rating points

    What Surface Balance measures

    How evenly the player performs across hard, clay and grass — an entropy-like measure of the spread, with a small penalty for extreme specialisation and credit for consistency across surfaces.

    It rewards a game that travels. It is a measure of balance, not of how good the player is on any one surface.

    A high score means performance is spread evenly across surfaces; a low score means it is concentrated. Neither reading says which surface a player is best on — that would need per-surface data the artifact does not publish.

    Across the 159 rated players this component contributes between 15 and 127 rating points — a spread of 112.

    Detailed evidence for this component is not currently exposed. It is computed from per-match detail that the published artifact does not carry.

  4. Era Normalization

    61.5rating points11%

    Score 41.0 out of 100 × weight 15% × 10 = 61.5 rating points

    What Era Normalization measures

    An adjustment against fixed era baselines and tour-depth proxies, so players from different periods remain comparable.

    It is what allows one 0–1000 scale to span the whole dataset rather than only the current season.

    The baselines are frozen, so this component reflects when a player competed and against what depth of field, not how they played.

    Across the 159 rated players this component contributes between 13 and 138 rating points — a spread of 124.

    Detailed evidence for this component is not currently exposed. It is computed from per-match detail that the published artifact does not carry.

  5. Match ContextLowest contribution

    46.8rating points9%

    Score 46.8 out of 100 × weight 10% × 10 = 46.8 rating points

    What Match Context measures

    How results compare with expectation once the round and the event are taken into account, so performance on bigger stages counts for more.

    It carries the smallest weight of the five, so it moves a rating the least.

    The round and event weights are calibrated in the pipeline and published as a single score; this page does not recompute them. Across the rated field this component varies far less between players than the others, so it rarely explains why two players differ.

    Across the 159 rated players this component contributes between 43 and 64 rating points — a spread of 21.

    Detailed evidence for this component is not currently exposed. It is computed from per-match detail that the published artifact does not carry.

Total component contributions

Published Racquet Rating
541.0 / 1000

The five contributions reconcile with the published rating to within 0.002 rating points — the artifact's own rounding.

Elo 1660.25 (career peak 2056.32) is one of the inputs to Performance Index. It is on its own scale, it is not a component of the Racquet Rating, and it is not comparable with the numbers above.

Component scores are 0–100; contributions are rating points on the canonical 0–1000 scale, model v1.1.0. How Racquet Rating works

Surface performance

Performance over the headline rating window. Rates are shown only where the surface sample provides sufficient evidence.

Surface performance over the rating window: 85 matches, 85 with a recorded surface. Surfaces played: Hard, Clay, Grass. Hard, 32 wins and 31 losses, 50.8 percent, 95 percent interval 39 to 63 percent. Clay, 3 wins and 11 losses, 21.4 percent, 95 percent interval 8 to 48 percent. Grass, 6 wins and 2 losses. No win rate is published: a rate requires at least 10 matches on a surface and this record covers 8. These rates describe this player only and are not used to rank players.

    Rate requires at least 10 matches.

    Why no percentage

    A win rate needs at least 10 matches on a surface to mean anything. This record covers 8, so the matches are shown and the percentage is not.

85 matches in rating window · 85 known surface

How surface performance is measured

These records come from the same canonical match observations as the headline Racquet Rating, over the same 85-match rating window. Nothing here is a separate rating.

A win rate appears only where a surface has at least 10 matches. Below that a single result moves the percentage by ten points or more, so the record is shown and the percentage is not.

The range beside each rate is a 95% confidence interval. It is wide on purpose: a surface record of a few dozen matches does not pin a percentage down, and the interval is the honest width of that uncertainty rather than a claim of precision.

Matches whose source records no surface are counted in the totals and assigned to no surface. They are never redistributed.

Surface rates are descriptive. They are not combined into a surface rating, and they are not used to rank or compare players — at these sample sizes most players' rates cannot be told apart.

Recent results

Last 10 matches: 5 wins and 5 losses, played Mar 2026 – May 2026.

How this record is counted

The last 10 matches this player actually played, from the same canonical match data as the headline Racquet Rating. Retirements count — a match was played and a winner advanced. Walkovers do not, because no match took place.

Match dates in the source are tournament start dates, so several matches can share a date. The order is reconstructed from the tournament and the round, which is why the record is shown as a total and not as a sequence of individual results.

The dates above are the span these 10 matches cover. For a player who has not competed recently that span can be well in the past, which is why it is always shown.

This is a record of what happened. It is not a prediction, and it is not the Form Momentum component of the rating, which measures something different.

How these are chosen

Every win this player recorded in the rating window against an opponent the source ranks, ordered by that opponent's official ranking in the week of the tournament, and limited to the 5 highest. Each opponent appears once, at that player's highest-ranked victory over them.

The ranking shown is the opponent's ranking at the time of that match, taken from the same match record as the result. It is not their ranking today, and not their career-high.

Retirements are included and marked. The match was played and a winner advanced, and it counts toward the rating this profile explains — but it was not completed, so it is not presented as though it had been.

This is a list ordered by one rule: how highly the opponent was ranked that week. It is not a judgement of which victories were the finest, and a higher-ranked opponent does not by itself mean a better performance.
