Fig. 1

Shown in log scale to highlight details at the low participation levels. We see that even at a 2% participation rate, the model still achieves 99% of the maximum attainable AUC. We observe this pattern across all the datasets studied. 80% of the whole dataset was used to train the model and the rest 20% used for validation.
