Do Resampling Estimates Have Low Correlation to the Truth? The Answer May Shock You. — Applied Predictive Modeling
We really shouldn't care about [lack of correlation between resampling estimate of ROC, and true values], or at least we are measuring the effectiveness in the wrong way. High correlation would be nice but could result in a strong relationship that does not reflect accuracy of the resampling procedure. This is basically the same argument that we make against using R2

[1608.06048] Survey of resampling techniques for improving classification performance in unbalanced datasets
"A number of classification problems need to deal with data imbalance between classes. Often it is desired to have a high recall on the minority class while maintaining a high precision on the majority class. In this paper, we review a number of resampling techniques proposed in literature to handle unbalanced datasets and study their effect on classification performance."
