Same here. The German Wikipedia page for LOC (http://de.wikipedia.org/wiki/Lines_of_Code) says that usually 10-50 LOCs per day are normal which would be 70-350 LOC per week.

seems okay to me.

Sometimes I hack away 100s of lines a day and sometimes I search for problems for days without writing a single (persistent) line of code.

I think the longest span I went was about 3 weeks till I tracked down a bug in a legacy system and wrote about 4 lines to fix it :D

And sometimes I search solutions to a problem for days which results in only writing a single line of code.
