  1. Similar analysis as Table 1, but with a normally-distributed length with a mean of 30 amino acids, and a standard deviation of 7. In this case, the posterior probability calculation shows slightly superior ability to distinguish between accurate and inaccurate placements than the likelihood weight ratio.
