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.)
