I can give you one anecdotal data point FWIW. I work 7-7 Mon-Fri, of which 75% is writing code and 25% is meeting. Beyond that I work at least 10 hours between Fri evening and Sun evening; 80% is writing code -- 20% will be doing some form of process. I work in a semiconductor company, at a fairly high technical level but I'm no superstar.
