My most recent job is billable and time is tracked in tight increments. Because I now pay much more attention to when I am and am not 100% engaged, it's been eye opening how much 40 hours really is. I've found that I'm about 2/3 efficient. So if I designate 6 hours for "work", I'm really working (and thus billing) for about 4 hours.

I would bet those 2 hours you aren't billing for are still actual work. You are available, you are probably thinking about the company/the job/the work. That is all WORK, and should be billed.

I used to do a lot of walks (before I moved from Upstate NY to Houston) where I would escape the code and think about the product. That was all billed time, and understood by my clients. Just because my fingers are not furiously typing, doesn't mean I'm not actively engaged in my work.

Sometimes. And in past jobs that's how I justified myself, sure I'm not hands on keyboard all the time but I'm "on" 95+% of my awake time.

This company's policy is the clock is only running if you're 100% engaged. I try to stick with that. As time has gone on I've gotten better about mentally turning the switch more all the way on/all the way off. There's some grey area on both sides that I figure comes out in the wash. And if I have a serendipitous moment, it's not hard to turn the clock back on and have at it.

It'd also look more different if the billing increment was wider. In a very past life I billed at 15 minute intervals. So if I was "on" for 12 minutes but stepped away to clear my head, the full 15 was billed.
