So you might notice that we have two ways of measuring total scores. One is the Survival Score (SurvSc). It's simply the sum of three components: Challenge Win% (ChW%), Tribal Council% (TC%), and Jury Vote% (JV%, irrelevant until the finale). So SurvSc = ChW% + TC% + JV%, for a max score of 2 (3 after the finale).
The other score is the Survival Average (SurvAv). It's a simple sum of fractional Challenge Wins (ChW), weighted TC Ratio (wTCR), and a weighted JuryVote% (to be exact, JV% times 6). Or SurvAv = ChW + wTCR + (6 * JV%). This has two advantages over SurvSc: (1) It's always a positive number (or zero), since tribal council votes are treated as a weighted ratio (instead of a potentially negative sum), and (2) it has a larger spread, and in looking at past seasons, we just feel it better represents the games we saw. As such, we've ordered the contestants based on this number. For their actual order of finish, see the Survivometer 19.
Neither ranking is perfect, however, and we're open to suggestions. Feel free to comment below with potential improvements.
*Scoring notes: In order to accommodate two medivacs, we came up with a new system for "voting out" people who are medically removed (neither Mike Borassi nor Russell Swan ever received a vote against them at tribal council, which made their TC scores artificially high). Our fix? Medivacs get credit for an additional (solo) tribal council, in which they receive votes against equal to 14 minus the episode they were removed. Borassi went out in Ep2, so he got 14 - 2 = 12 votes against. Russell Swan went out in Ep6, so he got 8 votes against. Nobody gets any credit for voting against them. This seemed to bring their scores in line with the people booted before and after they left, but we're open to other options, such as a unanimous vote against based on the size of the tribe at the time of removal, or something like that.

- 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.
- 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.
- 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.
