BAR Fight in 60 seconds, and the small print.

Where the data comes from

Active comparisons and statistics use GEX, a community project that extracts measurements and unit events from public replays. Earlier Supreme Isthmus captures remain archived for verification. They are not used in active GEX-only comparisons. Each match is counted once. Position playback uses recorded 30-second GEX observations; construction progress and simulation-based team coaching remain unavailable.

The official replay archive is the source of public games. This is not a complete record of every BAR match. Imports can be delayed, captures can be incomplete, and private games are not included.

Games, players and missing data

A game is one match. A player game is one player's appearance in one match: an 8v8 match can contribute 16 player games. Account IDs keep a player's history together when their name changes.

Coverage is the percentage of selected player games with usable measurements. Missing values stay missing; they are not treated as zero. A game can support an economy chart while lacking the unit events needed for an opening chart. Each chart keeps its own denominator, so different coverage percentages can be correct.

Openings and build timings

Our featured map answers use players with a recorded replay rating of OS 40 or higher, including exactly 40. That is a reference group of experienced players, not proof every choice was good. Explore lets you change it.

The first fighting unit means the first completed mobile fighting unit in the recorded event data. Commanders, builders, buildings and static defences are excluded. Units completed at the same recorded time are shown together.

Build timing uses the first recorded completion of the chosen unit or group for each selected player game. The typical time is the median among player games where it was observed. The middle half runs from the 25th to the 75th percentile. The percentage reaching a build uses all selected player games with usable unit events, including games where it never appeared. Games do not have to last 20 minutes to contribute.

Grouped constructors or economy buildings combine explicitly selected units with a similar purpose across factions. Their costs and abilities are not assumed equal. Receiving a unit and building it are different questions; transfers do not prove payment.

Map positions and game versions

We combine opposite starting spots only when the map layout supports that pairing. Unclear starts remain outside a named position. A starting spot gives context, but a player can change responsibilities during a match.

Map versions stay separate. Featured timing summaries can include several game patches; their labels say which filters were used. In Explore you can narrow an answer to one game version. A common timing is a description, not a deadline: pressure, teammates and enemy choices can make a different build appropriate.
