My IntraClade Coalescence (n) Age is similar to KenN's results as does mutation counting which is slightly older.

1,821.8___+-555.6 Max 3,070.6

Using IntraClade Coalescence (n-1) Age is more representative of a sampled population vs a whole population.

Ken's 111t spreadsheet also doesnt remove all of the Multi-copy markers.

...  As far as I'm aware Mike's magic spreadsheet stops at 67 markers, but if you know a way past that little wall,...
The R1b-P312xL21, R1b-L21, R1b-U106 and R1b-Early spreadsheets all have sub-sections/worksheets that can be reached by clicking on the tabs a the bottom. One of the tabs on the left is "Readme". All of the 111 (only) STR haplotypes are on the "ExtHts" tab. All haplotypes, up to 67 markers, are on the "AllHts" tab.  The "Clades" tab is another important one as it lists the STR signature (off-modal) definitions for the different variety labels.

Yep, Mike actually had explained that to me elsewhere, since I posted about it here.  Part of my problem is having old eyes; one of these Excel "workbooks" is a little like reading microfiche w/o a Reader.  So, I don't necessarily see something that says Read Me... also, ExtHts must mean Extended Haplotypes, but only if one expects it to; could be Extra Hots, or External Hits, or other things I don't need to see.

Eventually I'll get it, or so I must continue to hope.

Three total Hts would allow a nice modal age to be calculated for your variety. 111 markers brings down the number of generations per GD as well with an increased confidence level.

If that be the case, I'd like to see your modal age for Z220/L484.  I'm saying that to distinguish us, currently group Jra in the R1b-P312 and Subclades project, from various other L484s (including one guy, Moscia, elsewhere under DF27); so far, we haven't been assigned our decimal places, and Mike has dubbed us L484.NS, for convenience.  

We have four 111 marker haplotypes in our variety, representing separate families with no apparent relationships within "genealogical time."  (One has a no-call at DYS534, so his might be considered a 110 marker Ht.)  As far as I'm aware Mike's magic spreadsheet stops at 67 markers, but if you know a way past that little wall, the relevant Hts are numbers 962-965 in his R1b-P312xL21 Haplotypes file.  One more man has a 67 marker test, he's #967 -- but he is kin to me, so adding that Ht would skew the sample.

Not to say that all of time isn't genealogical, but that's a phrase people use.  Anyway this thread is about zeroing in on the homeland, not genealogy per se.  We've just about pared that down to Atlantic-facing Europe, woo hoo.
I've used  Ken Nordtvedt's Generations111T (http://knordtvedt.home.bresnan.net), so I gave it a go with L484. Putting your four 111 marker results ('Jra. R1b-Z220 / L484' in the P312 and Subclades project) through it, 'GA coal' (Coalescence) estimate was 1792 years ago, or 208 AD.  I entered the 'no call'  as 15 at 534, like the other three.

Using those four 111 marker results plus the one 67 marker result in Generations111T, the founder (GA) came out at 2539 years ago (around 539 BC) Coalescence (GA coal) came out at 1742 years ago (around 258 AD).

I'm responding to this thread because we had discussed a "no-call" on the test of one of our Richerts that has become a "call" (DYS534=15, as expected).  I guess that FTDNA kept re-testing his sample until they got a value for that marker.  I don't know when it posted, I just saw it today.
