How many documents being coded or what period of time triggers auto-refresh in Coverage Mode?

In Coverage Mode, the auto-refresh feature is triggered when either 100 documents have been coded or when 5% of the total documents have been coded, whichever of these two conditions occurs first. This mechanism is designed to ensure that the coding process is efficient and that users receive timely updates on the work being performed in real time.

The rationale behind setting these specific thresholds is to facilitate manageable increments of work while allowing users to maintain a clear overview of progress and coverage within the dataset. By focusing on a specific percentage of documents or a fixed number like 100, users can avoid being overwhelmed by too much data at once, thus promoting a more efficient coding process.

This approach contrasts with the other options listed, which either set different thresholds for the number of documents or the time intervals that do not align with the operational goals of Coverage Mode auto-refresh. By combining both a numerical threshold and a percentage, this correct answer strikes a balance that aids users effectively in their document review tasks.
