Personal Statistics
The Statistics page gives you a data-driven view of your chess performance across all your imported and recorded games. All figures update automatically as you add more games and run batch analysis.
Requirements
Section titled “Requirements”Accuracy, blunder, and mistake figures require batch engine analysis. Games that have not been analysed show only raw W/D/L counts. See Automated Analysis for how to run batch analysis.
Overview panel
Section titled “Overview panel”The top of the Statistics page shows your overall record:
- Win / Draw / Loss counts and percentages, with a colour-coded bar
- Split by colour (White and Black shown separately)
- Total games counted
Accuracy over time
Section titled “Accuracy over time”The Accuracy over time chart plots a 5-game rolling average of your accuracy as a filled area graph, so you can see whether your play is improving across a period or identify a slump after a long break. Accuracy is calculated from the engine classifications produced during batch analysis.
The chart has its own controls:
- A White / Black side toggle
- A time-range selector (1M / 3M / 6M / 1Y / All)
- A time-control filter
W/D/L by opening
Section titled “W/D/L by opening”The opening breakdown table shows your results grouped by ECO code prefix. Each row shows the opening name, number of games, and your W/D/L percentage as White and Black.
Use this to identify openings where your practical results are poor — these are candidates for deeper study or repertoire adjustments.
Recurring blunder positions
Section titled “Recurring blunder positions”When a position where you blundered or made a mistake recurs across your games (reached three or more times), it appears in the Recurring blunder positions list. Click an entry to open that game at the position on the Home page for further study — a direct way to find the mistakes you make repeatedly.
Luck and opportunism rates
Section titled “Luck and opportunism rates”These two rates are computed from the blunders and mistakes flagged during batch analysis:
- Luck rate: of your own blunders and mistakes, the percentage your opponent failed to punish (their following move was not itself flagged as a strong reply). A persistently high luck rate means your results lean on opponents letting you off the hook — fragile against precise opposition.
- Opportunism rate: of your opponents’ blunders and mistakes, the percentage you successfully punished. A low rate means you are leaving winning chances on the table.
High luck combined with low opportunism flags results that are likely to regress: you are being let off your own errors while not capitalising on your opponents’.
Filters
Section titled “Filters”Two dropdowns at the top let you exclude games from every panel at once — useful for leaving out games that would skew the picture, such as instructional games or a casual blitz folder:
- Folders — exclude one or more folders (and their subtrees).
- Collections — exclude one or more collections.
Both apply across all panels simultaneously. (The time-range selector on the Accuracy over time chart is separate and affects only that chart.)
