Somehow I doubt that the percentage indicator is any better. At constant 100% (or 50%) CPU utilisation, tracking the percentage, would you see a linear graph go

Somehow I doubt that the percentage indicator is any better. At constant 100% (or 50%) CPU utilisation, tracking the percentage, would you see a linear graph going down, hitting 0 as the machine shuts down? I've never tested that but it would be interesting to see the results for different models/OS versions.
