Maximum genetic distance within major R1b-P312 subclades?

[GoldenHind]

Can anyone give an idea of what is the maximum genetic distance found within some of the older subclades, such as L21, U152, DF27 and DF19? I am also curious if anyone could give me an average GD within the same groups. Even if no one has calculated it, I would appreciate specific examples of large GDs within these groups, such as a DF27 individual with a GD of 20 at 67 markers from another DF27 person.

I think the largest GDs being reported by FTDNA @ 67 loci in the R-DF49 project is 38 between kit no 188270 & 63595 and also 19499 & 63595

I don't even know how to tell, any more.  FTDNA uses a "hybrid" formula, but it's automatic and they don't really make the formula public.  Thing is, it's only automatic for administrators, and only for people in the group(s) they administer.  Ysearch GD is way too crude, doesn't include all of the 111 markers, and only works for haplotypes that have been entered there.

So, in that environment -- what's the question, again?
