~~ 2-3 hr code

Rest other related issues, documentation, test cases ...

Let's see…

• Handling customer issues: 1h
• Discussing/planning new features: 4h
• Coding: 2h

The rest is random stuff, not always, or not closely related to my work.

I plan for 4 hours a day. The rest piles up.

9.3 hours.

I'm not sure I understand ... there are 8 hour workdays?

One rule: think a lot, write less code !

Think twice code once.

Depend on the task, if the task is trivial you maybe don't need to think so much. If the task is big, and involve diverse parts of the app it's better to spend some time thinking and when you start coding do it the best at first shoot.
