% LOSSTABLE = GETAVGREGIONLOSSTABLE()
%
% Table of loss (drop) metrics per finite-capacity region and class, for
% regions that drop jobs (DROP rule). Each row reports the offered arrival rate
% (carried Tput plus drop rate), the carried throughput, the loss rate (region
% drop rate) and the loss ratio (LossRate / ArvR).
%
% Only regions with offered traffic are listed. The table is empty for solvers
% that do not track region drops: only the LDES simulation populates the FCR
% drop rate (self.result.FCR.DropRateNfcr).
