Summary

EOS test for three phases as in A13 of mace-mp0 paper. W, Mo and Nb are checked with one extra phase A15. I have not yest come up with a metric, hopefully we can think about it together.

To help to think about the metric and integration to the interactive app here is a plot that can be done with the results.

The performance varies quite a lot between the models, should be interesting to put a number on it. I attach also the reference data: equation_of_state.zip
I should be able to get similar data for Ta, non BCC Zr, Ti and maybe a couple of more metals.

Cannot figure out how to assign a new benchmark label to be in sync with the issue.

I think I finally came up with metrics that capture the range of performances that we see in that big plot in the summary. Here is the screenshot of how the table from my local app looks like.

I have not tried to add interactive plots yet and did not add any documentation. This is the plan for next week together with adding data for few other systems.
