The implementation of the range-based precision and recall metrics is quite
slow because it relies on the non-optimized ``prts``-package. To prevent long
runtimes caused by scorings with high precision (many thresholds), just a
specific amount of possible thresholds is sampled. This parameter controls the
maximum number of thresholds; however, too low numbers degrade the metrics'
quality.
