Larry hit the nail smack dab on the head. One thing to remember is that we are dealing with unphased data. From observing RAW DATA in my FF project, this is a big issue. It is also important to note that there can be thousands, I counted over 5,000 in my FTDNA v2 RAW DATA, nulls in the atDNA results. Note, these seem to be mostly false nulls. I have compared my atDNA results from 23andMe, FTDNA v1 and FTDNA v2 and at least 90% of my nulls show up on only one test. Nulls are typically ignored. Getting actual values for Nulls could impact these "matches" as well. I expect to have some Excel 2007 and higher functions and macros written in order to deal with some of these issues. I've been trying to write them but my dimly remembered 10+ year old Lotus 123 for DOS and dDase IV for DOS don't seem up to the job.
