Thanks James, for your clear answer. So to answer my original question,
looks like DNA Heritage has only processed maybe 200 or so 25-marker+ tests
through Sorenson Genomics, which might explain why we haven't heard any
complaints yet from their customers. Someone answered my earlier question
by lumping in all tests by Sorenson Genomics labs, including the SMGF study,
but is that fair? Can someone please verify if my earlier assumption is
correct, that people who were tested through the SMGF study are not allowed
to view their own results? If so, they would never be able to catch an
error, and we would not hear from any of them on this list, so their numbers
are irrelevant to my question.

Sounds like it might be fair to include Relative Genetics, however. So how
long has Relative Genetics used Sorenson Genomics as their testing
laboratory? We've heard examples of mistakes with Relative Genetics as
well, I wonder how their error *rate* compares to FTDNA?

Note: I keep putting asterisks next to the term "rate", because it the error
rate that matters not the absolute number of errors -- the reason, of
course, is that if two places have the same quality control, a place with
21000 tests should have 100x more complaints of errors than a place with
only 210 tests, but the error rate should be about the same.
