I think we have to stop looking at productivity as a universal metric. Each person defines his own way of being productive. Some people subscribing to deep work only consider deep work as productive work. If I can just write code in my comfort zone for 2 hours should I consider that productivity ? I'm not sure.

From my experience, a lot of a founder's time is spent in non deep work. Taking calls, traveling, talking to users, understanding user feedback, writing product features and coding up some or most of the features. So the actual deep work is perhaps very limited - in desiging features and coding them up. How do you measure founder producivity when the tasks are so varied. IMHO such a measurement exercise is futile.
