Scoring notes:
  • Ep2 voting: Not shown on the episode itself, but figured out via handwriting here.
  • Ep12: Aurora's extra vote: This was a really tough play to score. In the end, we went with counting Gavin's second Ron vote as Aurora's. She essentially split her votes, one for Rick (which would have worked if he didn't have an idol), and one for Ron.
  • The Ep7 and Ep14 re-entry challenges were scored as full individual reward challenges, not as duels, since they were multi-stage, massive builds, and there were so many participants (six and 11).
  • Adjustments for unaired reward challenge (5/26/20): Wardog's interview with Survivor Specialists revealed an unaired team RC at Final 9, which Gavin, Kelley, and Lauren won. Scores below adjusted accordingly.

Glossary of terms
  • Challenge stats
    • ChW: Challenge Wins. For tribal challenges, a contestant earns a fraction of 1 win, depending on if they participated (no points for sitting out). So in a five-person tribe's win, each participant gets (1/5) of a point, or 0.2 points. Duels (or individual RCs as in Ep1) at Redemption Island count as half a challenge (and half a win). Individual challenge wins count as a full point.
    • ChA: Challenge Appearances. Used to calculate ChW%. Fractional for tribal challenges (same as ChW), except sit-outs get charged for an appearance, because they could have participated.
    • ChW%: Challenge Win%. Simply, ChW% = ChW / ChA.
    • SO: The number of times a contestant sat out of a challenge.
  • Tribal Council stats
    • VFB: Votes For Bootee. The number of times the contestant has voted for the person who was ultimately voted out. Applies only to initial votes (no points for revotes in case of a tie). Special case: In a final three TC, where only one vote is cast (by the F3 IC winner), only that vote counts.
    • VAP: Votes Against the Player. The total number of tribal council votes cast against the contestant. Again, only initial votes count (no penalty for revotes), and here a hidden immunity idol (if played) erases the votes. In the special case of a final three tribal council above, only the F3 bootee receives a vote against.
    • TotV: Total votes cast during the tribal councils the player has attended (again, only initial votes count). Used to adjust for different vote totals as tribes shrink.
    • TCA: Tribal council appearances. The number of times a contestant has attended tribal council (at which they voted).
    • TC%: Tribal Council percent. Attempts to reward voting for the bootee (which players controlling the vote almost always do), while punishing receiving votes yourself. The formula is: TC% = [VFB - (VAP/TotV)] / TCA.
    • wTCR: weighted Tribal Council Ratio. Very similar in intent to TC%, but calculated as a ratio of VFB to VAP, while also scaling to a uniform number of TC appearances. The formula is as follows: wTCR =2* [VFB / (4+VAP)] x (14/TCA). I originally tried (1+VAP) to avoid dividing by zero, but this overly rewarded getting zero votes against relative to just one vote against, which seemed silly. (4+VAP) scaled that effect back comfortably. 14 was used as the scaling factor for TC appearances because there are usually 14 episodes, then a final scaling factor of 2 to bring maximal scores up to roughly even with ChW and JV% high scores.
  • Jury stats
    • JVF: Number of jury votes for the contestant to win. Maximum nine (Earl Cole, Fiji), theoretically.
    • TotJ: Total number of jurors. Necessary to not punish unanimous 7-juror winners (JT Thomas, Tocantins).
    • JV%: The percent of total jury votes cast for the contestant, or Jur% = JVF/ TotJ. This number is used, raw, in SurvSc, and is scaled in SurvAv (multiplied by six) to make it similar in size to ChW and wTCR.
  • Overall scores
    • Survival Score (SurvSc). It's simply the sum of Challenge Win% (ChW%) + Tribal Council% (TC%) + Jury Vote%, for a maximum possible score of 2 (3 after the finale).
    • Survival Average (SurvAv). It's a simple sum of fractional Challenge Wins (ChW), weighted TC Ratio (wTCR), and (eventually) a weighted Jury%. The latter two max out at six points total, for a theoretical maximum score of around 18 or so.
