High 90s and 100s mean you predicted a friend’s answers nearly perfectly — common with siblings, long-time best friends, or anyone whose snack order you could recite in your sleep. Ranges around 60-80% are the normal band for good friends: you share the big preferences and miss the small ones. Results under half usually mean one player was guessing from their own preferences instead of the other person’s, which is the fun of the game, not a friendship audit.
Two caveats keep this honest. First, this is our social reading of a ratio — only the game screen assigns the official result, whether that is today’s Friendship Card rank or the Compatibility Score the older listing described, and it may weight rounds its own way. Second, question packs change the difficulty: preference questions are easier to guess than secrets-themed ones, so a 55% on a hard pack can be a better run than a 75% on an easy one.
