Well, that number is computed from in the job objects and may not be stored in the stats collections.
I went digging around in the database for this and we just don’t collect that information. If you wanted to keep track of it, you’d have to implement an OnJobFinished script that would collect the information from say the job reports (so you could account for failed or re-queued tasks) and store that somewhere safe.
While you’re not supposed to poke around in the database, I’m including information here for educational purposes.
