  That link doesn't support what you're saying. Someone might be able to do that if they're monitoring power usage directly on the CPU with >microsecond precision for an extended period of time, not with a power metering plug that gives a fairly inaccurate reading at the wall every second or two, after having gone through the power supply transformers, rectifiers, capacitors, and containing noise from every other component in your device.
