It would be nice to learn exactly how "idle" time works? My understanding is that a period of inactivity will trigger the system to "go idle" and not record further activity. However, there seems to be a bit of a problem with how it works. For example (I just turned on Rescue Time) iTunes is listed as having about five minutes of "focus". This is rather off -- I certainly didn't spend five minutes searching my library for music!

What I suggest is that the "idle" work the same way the idle works on my bicycle cyclometer: after a period of inactivity (say, two minutes), all of the previous time is not counted. As an example: typing in Microsoft Word starts at 5.00 pm; last keystroke at 5:15 pm; idle triggered at 5:17 pm; time logged: 15 minutes (not 17.)

Or perhaps this is how it already works, and I really did surf my iTunes for five minutes? As I said, the first step should perhaps be a little more detail on how idle time works (definitely it was my first question when learning about Rescue Time.)
