Thanks for your comment and advice! It gives me the idea that I should perform a self-study. I can take two weeks "off" and work in complete isolation (during actual engineering time) and compare my productivity to the norm. I expect the difference to be negligible but I am prepared to eat my words if I am wrong. If anyone else is interested, I can write about this experiment and its results in a few weeks once I'm done with it. Replies here or emailing me will work.
