CMS-based inventories broadly agree between solutions and quantification algorithms, with all sites except for site 2 having an average percent difference of less than 50% between the four CMS-based inventories and their average. In particular, sites 1, 2, 3, and 5 have inventory values around or below 2 t/30 days and sites 4 and 6 have inventory values primarily above 2 t/30 days. This finding is in line with results from the previous sections showing that CMS rate estimates tend to disagree dramatically at the 30-minute scale (i.e., Figure ) but more closely agree in distribution over longer time periods (i.e., Figure ).
