@shorowit: I spent a while today going back through how I did this the first time around, I think I'm largely set up to redo the same simulations to derive the COP/UEF correlations we need. Before I do that, we should make sure we're on the same page about what to use for UA, since that will have a small effect on the correlations I come up with. Once we have that sorted, it's not too hard to rerun all the simulations and compile the results into the correlations we need.
