And that's probably a good thing. Presentation should probably be as aggressive as possible, ultimately. However I'm wondering whether it might make sense to apply the "slowly cooked frog" methodology here: if powertop initially displays all devices as 100% due to a very aggressive strategy, this might put off some people from trying to fix _any_ of the remaining problematic components of the Linux environment in their system since the situation seems hopeless (as opposed to a relaxed mode where _almost_ all devices show a suitable power status _except_ for some two or three "black sheep" and thus people have an itch to scratch - and then later once all devices have sufficient support, i.e. satisfying this more _relaxed_ powertop presentation policy, start introducing further powertop refinements which again make the weaker driver parts of the system stand out and get fixed again). Or alternatively make powertop support such a fine-grained display of various power management driver behaviour details that it's obvious which driver needs the most love.
