Only 3 of the 368 total peak values for peak 5 were absent or not detected. I still calculated the numbers with and without the zeros. There was very little difference either way.
Top graphic is the total count, and the mean for the individual dodecamers, n=6. Again, not a big difference, but clearly the n=6 gives the best values for variance and skew. Bottom three graphics are the individual values for each of the six dodecamers for peak 5 height.
Values for the first four decamers is posted here.
