What each panel actually counts
The connected-player count and the roster table below it can legitimately differ. The count includes everyone connected to the server, while the roster only lists characters that are actually in the world — a player still sitting at character select is connected but has no row there yet.
Each bar is the live share of currently connected players standing on that map, updated continuously — it's a snapshot of where the population actually is right now, not a historical average.
The chart tracks the online count over the last day, with the peak and lowest points called out below it — useful for spotting when the server is actually busiest instead of guessing from a single visit.
