Coding is different from normal work though, isn't it? I mean, if I have 3 hours of data entry ahead of me, I get in the zone almost instantly and crack through it at high speed with little difficulty, take lunch, then go on to the next thing. I've never had 3 hours worth of emails or administrative work to do, but I imagine it to be the same. 3 hours of solid code, on the other hand, takes a special day of the office being unusually quiet, at least half an hour to get in the zone, and at the end of it, I'm done for the day. It's not just my own arrogance, is it, to say that "code" work and "admin" work are two completely different categories that ought to be evaluated differently?
