If your tasks are basic, they are numerous, and that means a lot of communication, and that means you better be in the office. Besides, this basic crap is boring when done in solitude. On the contrary, difficult problems (difficult not in integration, but in algorithm) require total concentration and absense of distractions. Therefore you better not be in the office, and (more heresy) be totally disconnected. Turning off the interenet is a good thing sometimes.
