AutoQoS Cisco Phone Service-policy - policed default class rate

Hi,

I'm wondering first if I am correct in reading this Cisco Validated Design configuration as limiting everything but ef/cs3 to 10 Mbps on the example interface. So effectively all traffic to/from say, a workstation plugged into this switch, or a workstation daisy chained to an IP phone, which is connected to this switch, is limited down to 10 Mbps on this 1 Gbps interface? My understanding is service-policy will be applied before trust.

If that is the case, I'm wondering the reason for such a low rate?

The policy is assuming users don't normally have a need to sustain more than 10 Mbps, ingress.
