Investigating the accuracy/precision of the (the proposed weighting factor of Eq. (6) (S_r–N_c) for the condensate phase) for fitting on five employed literature datasets, namely (a) Dataset 1, (b) Dataset 2, (c) Dataset 3, (d) Dataset 5, and (e) Dataset 6. It should be noted that Datasets 4 and 7 were excluded from the analysis because they were not available for the condensate phase.
