What is thevROPs algorithm for calculating health children to parent?

[MattG]

I create "applications" by using Groups in vROPs.  The Group is a essentially a container that is calculating the anomalies, workload, and health from its children.   How are these metrics calculated in the parent?  For example if I have 3 child VMs with Health scores of 50%, 50%, 75%,  would the parent group show 58.3%?

If so,  should this be the same for any scores that are rolled up to parent?    Metrics such as anomalies are just summed up to the parent right?

Thanks,

Also,  do Hyperic metrics get passed up to VMs then to Group?   If not how do I get Hyperic metrics to rollup to vROPs groups?
