They were talking about the usual markers, so FTDNA's faster overall rate may change the equation somewhat. I would also compare living to ancestral haplotypes, in which case I would tighten it up by 1 or 2 for a genealogy of about 400 years. We haven't found any that had worse matches to the ancestral than 41/43 in 250-350 year genealogies.

33/37 marker test to really mean anything, and you need only concern
yourself with matches in the same surname.
