I must say as an hourly based freelancer (software engineering) for the last six years, I don't like this. One of the biggest perks is the flexibility to take time off whenever I want. If I don't work a full day in order to spend time with my kids outside because the weather is nice, then I do. If I want a day off, then I take it. As long as my projects are making progress or I give advance notice of long vacations, then my clients stay happy. That said, I'm not fixed on the billable hour which is why this article and comments are so interesting. So, I do thank you for sharing your method.
