After the TD methods were adjusted to represent a full-facility estimate, all independent estimates were averaged to produce the MEC typically one Solution 2 estimate and two adjusted Solution 1 estimates for each facility (see SI Section S-3.1 for exceptions). The MEC serves as a useful basis for plotting (X-axis in gures below) and for normalizing comparisons (Y-axis). However it is not used for comparisons. When comparing between any pair of estimates, each comparison was done with one TD method individually to highlight dierences between the TD methods.
