How many tasks +/- does it take to complete a "run"?

I would appreciate to understand how many tasks does it take to make a single composite "run"? While I suspect this can may vary based on the type of analysis being run, and may further evolve as time goes by... I know I "crunch" thousands of tasks, and I see the task id's increment... But an overall +/- current snapshot by application would be appreciated.

Sorry if this has already been published, I have searched the forums - unsuccessfully.

Inquiring minds...
