Right but those 10 iterations only take up prompt writing time. When the agent is executing I move onto other tasks in parallel. AI is faster when you parallelize your work flow.
Let me put it more explicitly. For one project I have 10 folders clones of the same project on my local computer. Each one of those folders is responsible for working on a different ticket/feature. I prompt one folder, move on to the next. It takes practice to get used to this style.
