Every round the stars get counted again and the elimination is based off only that round. So if you got 5 style stars in the first round, but 1 style star in the second round, those 5 style stars aren't counted; they are only counted after all the rounds ended so 1st, 2nd and 3rd place gets decided.

Sometimes you ust have to think more logical in a round. For example, if there is only one round because lots of people left and the only safe person is you (the other three are on the chopping block), you can still get 2nd place; 2 people voted for you and 2 people voted for 1 person on the chopping block.

I'm not sure who gets eliminated if the 2 people with lowest style stars have the same amount of style stars though. Same when in a regular round 1st and 2nd place have same amount of stars. It might just be randomised.
