There are some parallels. Haplogroup assignments are often predicted from
HVR1 (like the Y 12-marker test), and apparent matches with HVR1 can disappear
when HVR2 is tested (like going from a 12/12 match to a 21/25 match on a Y
test). Not all labs measure HVR2, but by far the most research has been done on

Yes, OA has illustrations of their reports for European and world-wide
haplogroups. The European network diagram is far more detailed.

I don't recall too many cases, but I don't recall any discrepancies, either.
There are no nomenclature problems, since you get the actual sequence.

I still recommend it as a good starting point. Sykes has a gift for
explaining complex material, expanding your world view, and making you curious about
your own ancestry. Some of the "sniffers" may object to the imaginative
narratives that Sykes provides for the seven daughters, but it's just a literary
device to emphasize that the clan mothers were real individuals, not just
