If they get at least as far as 23andMe, that wouldn't be bad, because 23andMe has me listed as R-Z18021, which is the same thing as FTDNA's R-BY166. That's just five steps upstream of my current Big Y-700-tested terminal SNP. FTDNA dates BY166/Z18021 to about 750 AD, which isn't bad.
Beats the heck out of R-M269.
It probably depends on the chip used at the time. 23andme has had 5 versions using different chips each time. It seems FTDNA has only had 2 versions of autosomal tests. The chips only scanned certain positions of the Y chromosome so data will be limited even with FTDNA.
The best thing about FTDNA is they have Y-DNA experts that know how to determine false negatives and false positives. I have identified several of them on the 23andme v5 chip.
