pod A uses 2 cores, pod B uses 1 core. Machine has 4 cores and all remaining unscheduled pods require 2 cores.

How do you attribute the partial usage of the node? Is it 2 cores billed to pod A, 1 core billed to pod B, and 1 core billed to some random team?

Or do you have 2/3 of Node billed to pod A and 1/3 of Node billed to Pod B.

Now deal with this permutation across all the various variables.
