Crispin and list Sure, adding carbon weights and ratios is fine. As near as I can tell this is already hidden in the 4.2 series from GACC.
Note there is a 4.2.2 that is a few weeks old. But I think char energy and energy ratios are also informative. Why not them too? Also already hidden in the outputs, and being used to report the key conversion efficiency value.
