I calculated who the statistically best competitors are based on their number of wins vs their expected number of wins
I only looked at people who won at least 4 HoH comps, 4 PoV comps or 6 total comps in a season. There is a ranking for individual seasons and careers. I calculated their expected wins by adding the likelihoods of them winning every comp if the result was random (if 10 people are competing in the comp, they have a 1/10 chance of winning which is .1 expected wins). I factored in them sitting out of comps when they were the previous HoH, battle backs and any other twists like battle of the block. I used the wiki to determine which veto comps they played in.
