Hello [~NSAmelchev],

Let's consider the following simple scenario: we have only one server node which is an affinity node and initiator as well. In that case, both metrics will be calculated on that server node. And so, metrics value will be broken, I think.
Moreover, if you have a cluster, you always can aggregate these metrics across nodes, and therefore, it is possible to calculate the number of _removals_ and _averageTime_ (see {_}ClusterGroup#metrics(){_})

Moreover, if you have a cluster you can aggregate these metrics across all nodes, and therefore, it is possible to calculate the number of _removals_ and _averageTime_ (see _ClusterGroup#metrics()_)
