Transmit power of Location Beacons

I’m a little bit irritated.

I set beacon’s transmit power to -40dBm.

In the cloud I can see the data:

Broadcasting Power  Weak (-40dBm)
Maximum Range  ~ 1 m / 3 ft

But in the Estimote App on Android I see:

Current power Weak(-40dBm)
Maximum range ~0.25m/ 1ft

Seems to be different. What is the correct range?
