In the first two contests, that would be a decent method. People were on the right track right from the start, and with the first contest, there were five people who had the top three, but in the wrong order, until someone guessed them in the right order. That's mathematically interesting (to me, at least, as a Math major in college), because there are only 6 possible orders for three items. So the winner may very well have wanted to put them in a different order than what he had, except all those other orders were already taken.
Anyway, with this week's contest, there are fewer trends ... or more importantly, fewer correct trends. I have a feeling no one is going to get it right, so we'll need to go to the tie breaker.
