@rsmith asked for something slightly different (but I am not sure how to collect that info): He wanted the AST size delta.

For what we have, I think the detailed results table would be more useful if we add some size metric for the files and the increase expressed as a percentage. Perhaps sorting by file size would help contextualize the significance of the percentage change.
