OBGG account ownership is accepted as requested. Only Solo/Duo games on the player’s official role are eligible. China and China Super Server are excluded by request. Empty history or an unknown account is missing evidence, not zero practice.

All 13 teams shown under the mini-program S16 tab were inspected. CFO’s POUT/Kino are absent from its displayed roster; TSW’s Eddie/Pun show no account. Other teams retain the original OP.GG source. This is not a complete account census of all95 starters, and retained public histories may not cover the full30 days.

Conflicting tags from other sites are diagnostic only and do not override OBGG ownership. Display dates lack year/timezone and are not used for filtering; complete match timestamps are. Accounts pool per person, then players are averaged, preventing account-count or volume weighting.
