I got more or less the same values (only with a network cable connected).
Low power standby: 0.5 Watts
How I get low power standby: when you turn off, press remote control power button for 5 seconds.
Description: Unit is shutdown, but you can turn it on with remote control, it will take some time to boot.
Sleeping: 5 Watts
How: when you turn off, press remote control power button.
Description: It’s sleeping, power on will be much faster, but still takes some seconds.
Idle in menu: 5 to 6 Watts
Description: It’s working waiting for menu commmands.
Playing a high bit rate movie: 5 to 7 Watts
If you have USB powered HDDs it can consume more (add the HDDs power).
So we can choose the power/usability profile we want.
-EDIT-
My “wattmeter” is a supermarket model it has 0.5 Watt precision.
