QOS police vs bandwidth - is this configuration wrong?

I understand bandwidth in QOS is use to guarantee a minimum bandwidth
I understand police in QOS is to set a limit to the maximum bandwidth.
class test_out
police **1608000** 50000 100000 conform-action set-dscp-transmit af31 exceed-action set-dscp-transmit af32 violate-action set-dscp-transmit 28
**bandwidth 2542**
random-detect dscp-based
random-detect exponential-weighting-constant 7
random-detect dscp 26 50 80 10
random-detect dscp 28 15 40 5
Can someone tell me if the above configuration is self defeating ?
I have a guarantee bandwidth of 2542Kb, but traffic is being police at 1608000 bits = 1570Kb

There is really a lot more to QoS than that.
I understand police in QOS is to set a limit to the maximum bandwidth.
Policing is dropping traffic that exceeds certain parameters.
To actually police, you need to drop traffic above your predefined bandwidth. You are still allowing all traffic, only setting the DSCP for traffic exceeding the bandwidth.
Normally, you use a priority queue to guarantee minimum bandwidth for a class, then drop any traffic exceeding the guaranteed minimum bandwidth. Do that in your policy map. For example:
policy-map Test
class VoIP
priority percent 23
police cir percent 23 conform-action transmit exceed-action drop
!
Your example configuration really isn't doing much for you.
