Iffy Match Lists: Why does GD/TiP fail to account for incompatible Haplogroups?

[Rheiner]

No. These are very old subclades. If a "match" means a relation 4000 years ago, it's meaningless as genealogy. FTDNA should write instructions that reflect that. Check the data at the link above, please?

[Rheiner]

We differ then.

If you had bothered to click on the link above, and examine the spreadsheet of 12 STR matches, you would see something that might surprise you. If 80% of "matches" are in different haplogroups, it's not a match list, it's a fantasy list -- because if haplogroups...

[Rheiner]

Thanks for that. What's chiefly misleading about the TiP are its claims of "precision."

But your story is outstanding.

[Rheiner]

Thanks for that, John.

The word "match" is misleading in this context, considering the instructions given customers from FTDNA.

Perhaps they will work on a better algorithm -- or at least better instructions. I'll add that there's no reason to have confidence in...

My kit has almost 1800 matches at the 12 marker level.

But many -- if not most -- are not true matches at all. And this seems to be a problem built into the FTDNA algorithm for matches.

I hand-sorted and checked each of about 300 BigY/TerminalSNP "matches": appx....

Well, Bartarl260, thank you for trying to be thoughtful. Bless your heart. Remember: This forum is for gripes.

I find these parts of your response inappropriate:

"That you don't like the answer isn't our problem, its yours."

"you should"...

[Rheiner]

"Because mistakes happen" is what started this thread. Remember? It's for gripes. And my complaint is that I can have no confidence in a test that, on its face, is flawed. Do you know what Haplogroup F is? Look it up.

Can you really not tell that your comment adds nothing to the...

[Rheiner]

Thanks, but this doesn't seem on point.

To be specific: I am classified as R-Z367 at the moment, downstream from U-152. But I am matched with a host of others who are downstream from U-106, or L-21, and so on. They are in different subclades entirely.

On my match list, matches...

Hi. I've been using the TiP report, as an easy yardstick for probabilities... but there's a glaring issue: haplogroup incompatibility.

The top name on my 67-marker match list computes much the same as the others on the list, despite the differences in mutation rate supposedly tracked by...

[Rheiner]

Yes, we do seem to use "different research methodologies." Your research methodologies may accept at face value a conclusion that a Swiss native is haplogroup F. Your research methodologies may even include paying for inaccurate tests.

Mine do not.

No more assistance...

[Rheiner]

In working over my match lists, it's become clear to me that just a little more information could go a long way.

My 67-marker match list has 10 matches -- but 6 are displayed as subclade R-M269. 3 out of 4 of the others are in different haplogroups from me. There's no way to divine which...

Well, then, the algorithm you've mentioned is either inaccurate or you're mistaken....
