Survivor: The Amazon boxscores Episode 10

Filmed: December 1-3, 2002 |  Aired: April 24, 2003
Auction time
IC: Rob wins
Alex out, 4-3

 

  • Reward challenge: "Auction" - Alex is screwed, then recovers. Jenna throws a tantrum because Christy wisely saved her money for letters from home, then is rewarded when everyone else declines to outbid her when she gets a re-do.
  • Immunity challenge: "Touchy Subjects" - Rob's fantasies about Heidi finally pay off.
  • Voted out: Alex, 4-3 over Matt.
Episode 10 scoring notes
  • Flippers may never win, but clearly, Rob took control of the game here, with a massive flip. And had Jenna followed through on quitting, or not stumbled into an F4 IC win, he would have gotten away with it, too. But this is Rob's high-water mark. An IC win added to a perfect Tribal Council record (7 VFB in 7 Tribal appearances, with zero votes against) gives him a massive 8.64 SurvAv score. Almost 2 points higher than his closest competitor. Pretty impressive.
  • Also, it's really remarkable how consistently terrible Heidi has been in challenges ever since the swap. Historically so, which is something of an accomplishment for an allegedly brilliant P.E. teacher, who ought to have both athletic and mental challenges locked up. Oh well.
Vote count:
  • Alex received 4 votes, from Matt, Rob, Butch, and Christy (voted out, 4-3)
  • Matt received 3 votes, from Jenna, Heidi, and Alex

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.
