Density	8%	9%	10%	11%	12%	13%	14%	15%	16%
90	0.786	0.893	0.821	0.821	0.786	0.714	0.786	0.786	0.750
95	0.857	0.821	0.821	0.821	0.750	0.750	0.750	0.679	0.679
100	0.750	0.821	0.857	0.643	0.750	0.714	0.679	0.679	0.679
Classic	0.714	0.643	0.679	0.714	0.714	0.643	0.643	0.643	0.679

Accuracy was significantly higher in the SNV method than in the classic method (permutation test, at ; at ).
