Do iterations running in real time take longer than "Gross Duration" + "Delay between Iterations?"

Hey, I just wanted to chime in and say that I completely agree with Tom_S's suggestion - it sounds like the best route to take. That being said, I wanted to provide some additional information about iteration tests. Just so you're aware, iteration tests do tend to take longer to run than regular tests, as there are additional setup, start, and stop iteration phases involved. So it's good to keep that in mind when planning your testing strategy.
