If I use a preferredDuringSchedulingIgnoredDuringExecution rule within a podAffinity, is the score of each node computed based on the number of pods on that node that match my rule? That is, would a node that has two pods that match my rule be preferred to another node which has only one pod matching my rule?

The podAffinity's design proposal algorithm suggests that it does not depend on the number of pods: Repeat Step 1a except replace the last line with "foreach node W of {N} having label [key=H.TopologyKey, value=any K such that M[K]>0], Y[W]++"

Is there a way to make a podAffinity rule that DOES depend on the number of pods in each node matching my rule?
