11am - 3pm, and a push 3pm - 4pm. Relief at 5pm and a slow cool-down.
A regular hour office job, but largely '50% time' which I'm ridiculously lucky to have, long may it be that way.
Evenings are a time for inspiration, and mornings for licking-off stuff mainly related to admin and documentation.
Time to work with and interact with colleagues is very important. It is a magnifier. What I've learnt the most regarding my own productivity is I do too much, and it is probably easier to have others do it. That's done by sharing and influencing, and helping out when colleagues are in need.
