My little contribution to the "how many matches" counting game: I've sent spit kits from each of the three PGSs to all of my kids' grandparents and one sibling each (and in one case, two siblings). When I go through them all and count up "everyone who shares more than 30 cM with us, collectively," I get (aggregated over these 27 exomes) . 160 "public" matches on 23andMe (of which >80% have "shared") 112 matches on AncestryDNA 36 matches on FTDNA. I find the chances of "solving" them (identifying a paper-trail genealogical relationship) is pretty decent for anything over 60 cM: of the 39 matches who meet this criterion (out of ~300 mentioned above (some of the matches are on more than one platform)), 23 are solved (mostly all 4th cousins or closer). Of the 16 remaining >60cM ones, the main problem is "non-responsive + private tree" rather than "we can't figure it out no matter how hard we try" (of which "adopted match" is a subset). Of the <60cM matches, my solve rate peters out quickly as of yet. I don't see the solve rate among these 39 >60cM "high matches" differing much between the three PGSs. Best, Eric
