Two boards visible in the lobby
The labels do not establish lifetime accumulation, reset timing or aggregation. The selected Spanish build shows Más Aura (Most Aura) and Mayor tiempo de juego (Most Playtime). These are distinct labels: aura and time played should not be treated as the same ranking criterion. The official description also says players earn rewards and climb leaderboards.
What this page can tell you
Look for the matching board heading in the game before comparing values. A round's displayed aura result is not itself a rank threshold. This site does not provide a live player leaderboard, update cadence or reset schedule, and it does not claim those fields are absent from the game.
Ranks
No exact-game table of named ranks, required aura or rewards was located in the checked sources. The existence of a leaderboard does not establish Bronze/Silver/Gold ranks or any other ladder. A target-game UI capture or developer announcement is needed before such values can be published.
