Yes, that is correct. The current version (v1.0.1) currently does not maintain a running history of task durations, only the last execution duration. Historical trending of publisher task duration is a high priority feature in our tracking system and we intend to address it in a future release. It would be helpful to know how large of a history window customers would like to maintain (e.g. past 30 days? configurable window size?) and if aggregation on past time windows would be useful.
