When you get to the bottom of a hole, stop digging. Project status: I've got 947K points total for glycine gamma-polymorph less 13,000 points that must be rerun (about 6 hrs). The 302K new points will be added to the original stack, duplicates (there should not be any, but "should" is not good enough) will be removed. Least squares fit for slope and intercept, then graph the points. If it mirrors theory, even better. gamma-Glycine is nice because compute time varies as atoms/volume and (radius^2). A very tightly packed crystal lattice is faster to compute to a given number of contained atoms. The published paper

recommended alpha-quartz for the parity Eotvos experiment challenging fashionable gravitation theory. It is commercially grown to high specs. Folks know how to shape it to lamba/20 accuracy, how to gild it (100 nm titanium tie-layer), and it doesn't outgas gas in hard vacuum. Quartz is crunching away in my garage for the next 110+ days. I've got two volunteers with cluster access, so that could substantially contact.
It's been wonderful! Everybody was splendid. We are pushing the paper to have the experiment performed in (reluctant - Not Invented Here) academia. Only technical objections matter. I'll have a couple of Hypography-sharpened sticks to make the pigs squeal.
I'll post a link to the graph when the data is fully arrived and massaged.
