Players with similar ELO profiles:
Tessa's SHALLOW rating is calculated using the Elo rating system applied to Survivor gameplay. Every tribal council generates pairwise matchups: correct voters beat incorrect voters (Outwit), survivors beat eliminated players (Outlast), and jury votes create head-to-head matchups at Final Tribal Council. The K-factor is 8, empirically optimized across all seasons.
All players start at 1500. Returning players carry their rating across seasons. Players with fewer than 5 tribal council attendances are marked provisional. Read the full methodology.
