 - API: PUT Job/status
 
-  Estimated throughput: at most one API call for each Job Pod reaching Ready
-  condition.
+  Estimated throughput: at most one additional API call for each Job Pod reaching
+  Ready condition per second. The reason is that the update of the `.status.ready`
+  field triggers another reconciliation of the Job controller.
+
+  In order to constrain the number of reconciliations, the Job controller
+  batches and deduplicates reconciliation requests within a second.
+
+  In other words, if there is another reconciliation request planned within a
+  second, the one triggered by `.status.ready` update is skipped.
