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.

Career MPF notes: Only 64 contestants meet the minimum requirements of appearing in at least two individual challenges in two or more seasons. (We set the bar this high to avoid instances of someone setting a spectacular mark in their first season, then not affecting their career numbers by getting booted before appearing in an individual challenge their second. Mostly, this just screws over someone like Terry Deitz. Sorry.) The median sits at 64.3%, which is higher than the single-season median of 55%.

• 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.
