Seed sensitivity. Sensitivity curves for multiple spaced seeds with 1, 2, 4, 8, and 16 seeds of increasing weights: 11, 12, 13, 14, and 15, respectively. The length of the random region is N = 50 in the left plot and N = 70 in the right plot. In both cases, doubling the number of seeds outweighs the increase by one in the weight and therefore the sensitivity increases.
