What do we mean by MPF?
MPF, or Mean Percent Finish in individual
challenges, is a simple measurement of individual challenge
proficiency. Someone with a 1.000 MPF has finished first in
every individual challenge in which they've competed.
Finishing in the middle of the pack every time will net you a
score around 50%. And so on down from there.
While simply totalling challenge wins is a handy shortcut, we
feel this is a more comprehensive measurement of challenge
success. Maybe someone is good at standing still, or holding
balls aloft, but can't solve a puzzle to save their life. That
may be hidden when comparing challenge performance by simply
adding up challenges won, or even calculating challenge win
percentage. In contrast, MPF includes the challenges the
contestant didn't win. So there may be a few surprises. For
example, despite Kelly Wiglesworth memorably ending Borneo
with a five-challenge win streak, that performance is only the
61st-best overall (!), because she under-performed in several
early post-merge challenges (she still makes the career
leaderboard, though). We've added MPF totals to all the single-season
scoring data, so if you don't see someone you expect
here, check that season's complete scores.
Single-season data summary: Over the first 32
seasons, there have been 261 contestants who appeared in four
or more individual challenges in a season. Of those, the
average MPF score is 0.563, and the standard deviation is
0.140. There have been 41 contestants with an MPF at least one
SD above the mean (greater than 0.703), who would be strong
performers. Conversely, there have been 50 contestants whose
MPF has been lower than one SD below the mean (less than
0.423); they fared particularly poorly. (There are six
contestants at > 2 SDs above the mean, three at < 2 SDs
below the mean, mainly because it's difficult to get a really
low % Finish.)
Glossary of terms
- MPF: Mean % finish - mean of all %
finishes in individual challenges. Essentially how close the
contestant comes to winning any random challenge (1.00 is a
win; 1/[# of participants] is last place).
- ChA: Challenge Appearances. The number of
challenges in which they competed.
