Some background on this: I run 3-4 coding agents in parallel every day, every morning I ask myself, what realistic goal can I deliver during my 8h working time? Thus at the beginning of the day, I will always work with my coordinator agent, to pick up today’s task queue, estimate them and go on execution.

If you ask an AI agent how long a task will take, it answers in human time, so the gut number is that’s an afternoon when the real answer is 20min. I have run it for a few months now, with a few hundred real dispatches. With better estimation my morning plan and my end-of-day reality mostly line up now, and when they don't it's usually because something finished faster than I guessed, not slower.
