Normalized Root Mean Square (NRMSE) criterion is used to generate the fit % number. It is a measure of how much better the model is in reproducing the observed data relative to the mean of the data. This is what is called the 'Fit to Estimation Data'. See:

Can you tell me where you see the 'Best Fit' to the model?
