The modal value (i.e., the single most common value) for DYS447 is 25.
SALTIDOGGY (Herbert) is lower by 5 and you are higher by 6. Both values are unusual,
but the larger the sample size, the more likely we are to encounter rare

In Herbert's case, a number of people had the same value, so it's not likely
to be a laboratory or clerical error. But if you match someone in your group
on every marker except one, and you have a big difference from them at that
locus, then it's worth double-checking with the lab to confirm your results.
