-The next plot is the exact same data and queries fed to the REQ sketch set for High Rank Accuracy (HRA) mode. In this plot, starting at a rank of about 0.3, the contour lines start converging and actually reach zero error at rank 1.0. Therefore the error (the inverse of accuracy) is relative to the requested rank, thus the name of the sketch.

Therefore the error (the inverse of accuracy) is relative to the requested rank, thus the name of the sketch. This means that the user can perform getQuantile(rank) queries, where rank = .99999 and get accurate results.
