Stat Glossary
Below is every abbreviation used across the five strategy views, with a definition and a plain, everyday explanation. Use it as a reference — you don't need to read it end to end. Every stat is a percentage; turn on Breakdown to see the raw counts behind each one (see Reading the Colours).
Serve & return core
These are the headline stats — they appear in Key Stats and across the specialist views.
| Abbrev | Full name | What it means | Plain explanation |
|---|---|---|---|
| SH | Service Hold % | Share of the player's own service games that they win. | How often this player wins the games they serve. Higher = harder to break. |
| SPW | Service Points Won % | All points won while serving. | Out of every point on their serve, how many they win. |
| RPW | Return Points Won % | Points won when receiving the opponent's serve. | How often they win a point on the other player's serve. |
| BPS | Break Points Saved % | Of break points faced on serve, the share saved. | When they're in danger of being broken, how often they wriggle out of it. |
| BPW | Break Points Won % | Of break points earned on the opponent's serve, the share converted. | When they get a chance to break, how often they take it. |
| OpH | Opponent Hold % | How often this player's opponents hold serve. Good when low. | How often the other players manage to hold serve against them — a low number is good. |
| FS | First Serve % | Share of serves landing in as a first serve. | How often their first serve goes in. |
| FSPW | 1st Serve Points Won % | Points won when the first serve is in. | When their first serve lands, how often they win the point. |
| SSPW | 2nd Serve Points Won % | Points won on the second serve. | How well they cope on their weaker second serve. |
Set-pattern stats
These capture what happens at key moments — closing sets out, coming back, holding under pressure. They power the specialist views. Set patterns happen far less often than points or games, so watch the counts in Breakdown.
| Abbrev | What it means | Plain explanation |
|---|---|---|
| BaBB | After being broken, breaks straight back before the set ends. | When they lose their serve, how often they hit straight back. |
| WFS | Wins the opening set. | How often they take the first set. |
| WS1W2S | Wins set 1, then wins in straight sets. | After taking set 1, how often they finish the job quickly. |
| LS1WS2 | Loses set 1, wins set 2. | After dropping the first set, how often they hit back to take the second. |
| LS1FBS2 | Loses set 1, gets the first break of set 2. | After losing set 1, how often they strike first in the second. |
| LS1BFS2WS2 | Loses set 1, is broken first in set 2, still wins set 2. | A deep fightback — behind and broken, yet still takes the set. |
| LS1BFS2BB | Loses set 1, is broken first in set 2, breaks back. | Same tough spot, measured by whether they claw the break back. |
Identity columns
| Column | Meaning |
|---|---|
| Sched Time | The match's scheduled start, in your own local time zone. |
| Player | The player's name, with an ⓘ icon to their full stats page. |
| Odds | Decimal price; lower = favourite. A dash means no price yet. |
A good place to start as a beginner: learn SH, SPW, RPW and BPW first — they describe most of a player's serve-and-return strength. The set- pattern stats add detail once you're comfortable.
