Before revision:  They are empirically 225 and 1350 fold faster than piRNA. A correlation of 0.855 and 0.836 was achieved between piRNA and BPPart and between piRNA and BPMax, respectively, in 37 degrees on 50, 500 experimentally characterized RRIs. Those correlations increase to 0.920 and 0.904 in -180 degrees.
