I wish I saved one of the so-called pathological matches because then it would be easier to see exactly how it is failing. I'll do my best from memory.\r\n\r\nIf the first match is an excellent pathological match, then it is conceivable that continued attempts at matching where you land on accurate matches are thrown away, even if you would build a much larger consensus had you landed on an accurate match. If I remember correctly, I'd get maybe 3-4 points on a pathological match, while if I re-ran and got lucky, I'd get a dozen matches on accurate points.\r\n\r\nI think the easiest way to reproduce that would be a translation of 1 small square with no rotation. However I may not remember that  right. "}}
