-CC* a model-independent measure of noise is in the diffraction data. CC* is higher than CCwork in whole resolution range (except the shell 2.0-1.9 Å where CC* is undefined due to negative CC1/2. Thus, the overfitting was not indicated. To access overfitting, it is not needed to test set, so the comparison of CC* with CCwork is much better then with CCfree as CCwork is calculated on more data.
+CC* is a model-independent measure of noise is in the diffraction data. For this data set, CC* is higher than CCwork in the whole resolution range, except the shell 2.0-1.9 Å where CC* is undefined due to negative CC1/2. That means overfitting was not indicated but the shell 2.0-1.9 Å should be discarded because these data are very noisy. Note that to access overfitting, it is not needed to use test set, so the comparison of CC* with CCwork is much better than with CCfree as CCwork is calculated on more data.
