A neat feature in CA:DE is the ability to visualize the recent and all-time efficiency percentage of economy units and production/research buildings, where efficiency means the time spent working vs the time being idle.
Pro users can bring up the efficiency chart, click on an economy unit or a building, and then click its efficiency stat near the entity's HP.
The selection panel will now display two pie charts: one for last-minute efficiency, and another one for all-time efficiency.
Hint: Choose many units or buildings to assess the overall efficiency rate of a group!
The pie chart provides a handy legend section that breaks down the selection's activities during each chart's respective time durations.
Striped slices indicate some sort of non-productive activity, such as time spent walking by villagers, or idle for economy units and buildings.
Larger striped slices in the all-time chart of units or buildings meant to be constantly working indicate a macro issue, which a player could use to diagnose why their economy is not growing as quickly as it could.
Last-minute charts are much more likely to fluctuate from moment to moment, but they are useful for diagnosing specific issues more precisely once a broader pattern is identified by the all-time chart. An example of this could be villagers starting to bump too much on a woodline or taking too long to walk back to deposit resources.
