I'm not sure I agree with your statement that virtually all of the R1b in Y
Search comes from guesswork and probabililty assumptions. The later yes,
but not guesswork. I have been assigned as R1b by FTDNA based on my STR
results. This was based on comparisons with their database. I also come
out as R1b on Whit's haplogroup predictor. So, I am an R1b with a very
high probability. However, I do agree that SNP testing will remove the
small probability that I am something else (which is why I'm waiting my the
results of my SNP test). I do also agree that there needs to be a way of
seeing how the haplogroup was assigned.

Unless one is tested specifically for M269 then they are guessing. FTDNA
tests for P25 only. Virtually all of the R1b in Y search etc. comes from
guesswork and probability assumptions based for example on matches in the
FTDNA Haplogroup database. I am as guilty as the rest since I placed "R1b"
there prior to being tested for P25 or M269. There needs to be a way to
indicate clearly whether one was SNP tested and by which lab.
> Recently our lab tested 8 people for M269 (myself included) and all were
positive for this marker. As far as I know only they have the "proper
authority" to put R1b1c into Ysearch. In a few days I will provide details
as to how other people can have this or virtually any published SNP marker
