Before revision:  Probabilistic profiling of the occurrence of 3-10 and Pi-helices reveal their presence to follow Poisson flow on the sequence. With extensive analysis from varying standpoints we prove here that, such Poisson flows suggest the 3-10-helices and especially Pi-helices to be evidences of nature's mistakes on folding pathways.
After revision:  Probabilistic profiling of the occurrence of 3-10 and Pi-helices reveal their presence to follow Poisson flow on the primary structure; implying that, their occurrence profile is rare, random and accidental. Structural class-specific statistical analyses of sequence intervals between consecutive occurrences of 3(10) and Pi-helices to be evidences of nature's mistakes on folding pathways.
