• Ep. 2 Reward challenge: Champions pro athletes are good at athlete-ing, win comfort items.
• Ep. 2 Immunity challenge: Finally, the Contenders actually win something.
• Ep. 2 voted out: Russell declines to play his idol, is out 4-4-2-2 (9?-1 on revote).
  

Notes: The Tribal Council vote was super-confusing, because only the revotes were shown at the end, during Russell's final words (and then only some - neither of Commando Steve's votes were ever shown, so we have to assume his revote was for Russell). So for the purposes of assigning VFB credit, the original four votes for Russell required a bit of sleuthing to nail down, apart from Moana's which was shown, along with her epic confessional: "You've played the game three times and never won, mate. Maybe go home and review it and try again?" Shane's turns out to be the next easiest: The voting confessional shown at the end is actually from her first-round vote. Sharn's can be matched because her second vote looks almost identical to her first. Finally, Sam's surprise vote is identifiable because we can see the stains on his parchment when he votes the first time, which match the final Russell vote. Also, the handwriting on his revote is a good match. (Thankfully, we don't have to identify the rest, of which Lydia's vote for Damien and Mat's vote for Jackie are the clearest, based on their handwriting.)

*Update (8/10/18): From Moana's exit interviews, Brian was supposed to vote for Russell, but flipped and voted for Jackie.

• 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.
• Plc: Place finished in an individual challenge
• %Fin: Percent finish - roughly, percent of a win achieved, with 1 being 100%.
• MPF: Mean % finish - mean of all % finishes in individual challenges.

• 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.

• 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.
