As I was adding up the new numbers, I was surprised because I've seen several posts around the net where people talked about gaining 4th cousins. For five of my tests, though, I lost a significant number of 4th cousins. (I don't know yet whether they were demoted or wiped.) It was then a surprise to get to the sixth test - my own - where I didn't lose any. (Well, technically I lost two, but I "gained" two that were smacked down from 3rd cousin status.)

Percent Lost / Current Matches

Me: 67% (4442 matches now)

Mom: 72% (4958)
Maternal Grandmother: 68% (4865)
Maternal Uncle: 74% (4396)

Dad: 77% (2881)
Paternal Great-Aunt: 78% (3593)

Only my great-aunt had 2nd cousins demoted: 2 out of 4

All six tests saw 3rd cousins demoted - anywhere from 1 for my mother to 7 for both my uncle and my grandmother.

Number of 4th cousins lost:

Me: 0

Mom: 40 (11%)
Maternal Grandmother: 73 (19%)
Maternal Uncle: 112 (34%)

Dad: 75 (41%)
Paternal Great-Aunt: 118 (39%)

(It's pretty even when comparing Extremely High to the former 96% and Very High to the former 95%):

I haven't had a chance yet to see if I've retained matches who are at GEDmatch, especially those on triangulated segments. Blaine Bettinger has an informative post that says what the cM should be like for each of the new categories: http://www.thegeneticgenealogist.com/2014/11/19/goodbye-fals...

Beware, though. The first and only person so far that I've looked at shares 24 cM over two segments (15 cM and 9 cM) at GEDmatch. However, here she's ranked as "Good" and not "High," per the chart. Oh, this should be fun... :)

[ETA: I'm not saying that Ancestry is wrong to mark that match as "Good." The two segments are not triangulated and could be in an area that raises flags, or may be measured differently at Ancestry, etc. I'm just saying not to assume that you share a certain amount of cM because of the chart.]
