To interrupt your discussion, I check FF haplogroup growth in blocktree. FF users usually are labeled unknown. However, there are some people that have both autosomal and STR too, so they are able to enter paternal place. Some of them do it, just small percentage leave unknown. It would be best to know the state of haplogroup before the FTDNA announcement. However, more or less, you can judge those with FF only by uknown marker.
