From the FAQ: Q. What exactly is the number in parentheses in "39.4% (115.6) foo: bar"? A. It's the number of wakeups per second and per CPU core.
I think this is potentially a problem. If you send someone powertop -d output e.g. as a bug report, the output doesn't say how many cores you have, and for the purposes of fixing software the relevant figure is usually the *overall* number of wakeups per second.
I wouldn't like to suggest changing the displayed units, and wakeups/core are probably more relevant to the individual. But I think it might be worth adding "cores:" to the summary line, so you can multiply the per-core figures in an arbitrary dump.
