Google Hangouts Video Data Usage

[regression]

Can anyone give me a ball park how much data would be using by Google Hangouts on a video call? I would like to use it over my mobile data, but I would like to know ahead of time what to expect. For example, 10 minutes would equal about how many megs?

This from Google's Hangouts page:

The bandwidth used by Hangouts is adaptive and will vary to provide the best experience for the given conditions of the participants’ network. Here is a guide for the minimum and maximum bandwidth requirements and expectations:

Minimum bandwidth required:

Outbound from the participant: 300 kbps
Inbound to the participant: 300 kbps
Ideal bandwidth for the best experience:

Outbound from the participant: 2.6 mbps
Inbound to the participant: 2.6 mbps
With group video calls of more than 2 people you can expect bandwidth usage in ideal situations to be:

Outbound from the participant in all situations: 2.6 mbps
Inbound to the participant with 5 participants: 3.2 mbps
Inbound to the participant with 10 participants: 4.0 mbps

So, if you're only using it for a one-on-one, you'd be using around 4.5 Megabytes per minute in a very crappy connection (300kbps up/down, 2.25MB per minute per channel), and around 39 Megabytes per minute on a very good connection with very good HD video (2.6Mbps up/down, around 19.5MB per minute per channel).
