Not so surprising, given the "haplotype diversity" we find in databases.
There are many people who can find no matches, even at, which uses
only nine markers in most cases. The current state of the Eurasian samples
has 22,970 records, with 10,520 *distinct* haplotypes. That means that there are
many cases where a haplotype is represented by just one sample. Every time a
new population is added, there are novel haplotypes. Each additional marker
you add increases the number of distinct haplotypes, too.
