Same MO,  but since this peak appears 100% of the time (so far) there is no second column where the mean (and other parameters) is calculated excluding the missing (undetected) peak values.  Difference in CRD peak width is certainly not very different from the first 6 dodecamer summary than the first 8 dodecamer summary. Some benefit is gained by using the means of each, rather than the individual trimer values.
