At the website http://www.survivormetrics.com/ a formula was made to determine the best physical threats based off the IQ test. The website has not updated since season 27 ended, but I have received permission to use the formula and post results (and give credit to the blogger who made the formula).
With eight people left the first challenge was for 4.5 points. Losers lost 0.64. Jay won it. Ken then won a challenge worth 4. Losing would cost 0.67. The new score is.
Jay is well in the lead, but he may need to win out.
