I think they made it unnecessary complicated by the way they've presented the results. They had two results graphic, kinda like this:
Save | Evict |
6% | 21% |
30% | 36% |
26% | 16% |
38% | 27% |
And then the final results, which were like:
And it used to throw me off as well on how somebody that had 36% evict votes and 30% save votes could end up with 17% of save votes.
But it's because the save votes in the first graphics are based on the total number of save votes and same for evict votes (e.g. Person 2 got 30% of all save votes, not 30% of their total votes being save votes). And then the second graphic is calculating the percentages of the votes that didn't cancel each other out.
@jessy_girl it might become clearer if we take an example with the actual number of votes, not percentages.
Save | Evict |
11 | 21 |
54 | 37 |
47 | 16 |
70 | 28 |
So there are a total of 182 votes-to-save and 102 votes-to-evict.
Housemate 1 got 11 votes-to-save, which means they got (roughly) 6% of all votes-to-save. They also got 21 votes-to-evict, or 21% of the total votes.
Housemate 2 got 54 votes-to-save or 30% of all votes-to-save.. and so on..
Now we calculate the difference between all the votes and get these final results (with a + meaning it's more votes-to-save and a - meaning it's more votes-to-evict)
11 - 21 = -10 |
54 - 37 = +17 |
47 - 16 = +31 |
70 - 28 = +42 |
After calculating the differences and cancelling out votes, 100 votes remain.
Housemate 1 got 10 votes-to-evict or -10% of the overall remaining votes.
Housemate 2 got 17 votes-to-save or 17% of the overall remaining votes.
And so on...
Since housemate 1 has the smallest number, they are evicted. In the case of a double, housemate 2 is also evicted, because it's the next smallest number of votes.
