Recoverpoint long term statistics

I am trying to study the overall WAN link utilization as well as identify which Consistency group is the bandwidth sucker.

I am looking at the RPA Long term stat tool.

For overall WAN link utilization, can I use "WAN throughput from site" stat to find out the overall utilization.

As to identify which consistency group is the bandwidth sucker can I use "Non - initialization output rate for link" stat instead.

There are many stat available so I am trying to find a more relevant one.   The Non - initialization output rate for link will probably include CDP and CRR traffic
