# Run detail

One learner's run of one simulation: timeline, skill mastery, event log and replay.

A run is one person playing one simulation once. Every analytics page in HyperSkill leads here: from a simulation's user sessions, from a lesson's learner progress, from a group session's learner list, or from a learner's own summary.

## At the top

* **Started**: when the simulation was started.
* **Duration**: how long the simulation lasts.
* **Device**: the device the user was using and its operating system.
* **Total actions**: the total number of actions the user performed in the simulation.

When the simulation has a competency model, **Overall mastery** shows the learner's score for the run.

## Skill mastery

Each skill in the simulation's competency model, with the learner's score for this run and how it changed from where they started. Runs from a group session also show **Skill vs group average**, comparing this learner with everyone else in that session.

## Timeline

The sequence of key moments within the simulation: when it started, quiz questions and responses, each skill that moved and by how much, feedback the learner was shown, and when they finished or left. Hover a marker for the detail.

## Event log

Everything recorded during the run, in order, with the time it happened on the device and the time it reached our servers. Expand a row for its fields. This is the raw material the timeline is built from; see the Event reference for what each event means.

## Replay

For any 3D simulation run, a replay shows where the learner was and where they were looking, played back inside the simulation. Scrub the timeline to move through the run.

* **W, A, S, D**: move your own view.
* **V**: toggle your camera between third person and first person.
* **Right click and drag**: look around in third person view.

### Gaze Heatmap (experimental)

In the replay card you can toggle a gaze heatmap on and off. When it is on, you can see where the user was looking and where their focus was during the simulation.
