mt FTDNA: copy of 2026-10-12

2026-10-08 → 2026-10-12

Comparison of two consecutive copies of the FTDNA tree. Branches are matched by internal id, kit counts per country come from the per-branch counters. A country's growth is the sum over all branches. The number can also be negative: kits leave the public tree when a customer hides their results or deletes the account, and most of those kits have no country.
