Don't say your predictions will turn out to be true. Anything can happen at the ACTUAL competition. Evgenia may have a meltdown at Worlds, or she may have a great performance but get lower scores and thus not get a world record score. And also, if she does actually get a world record score, many viewers will find it unacceptable and probably have it cause multiple internet rants happening. Now that's what I would call an uncomfortable WR. Evgenia is a talented skater, but her level is just simply not WR level yet. And as penguin said, Yuna did not bomb her first Worlds. Neither did Mao actually.
Yuna set a WR (at the time) in the SP and while she fell twice in the LP, her other elements were still good and she ended up having the 2nd highest PCS in the LP and won the bronze. Mao may have not had the best SP, but she won the LP by 6 points and in the end lost the gold by just 1 point. I consider bombing to be messing up on most of the elements, but that wasn't the case for Mao or Yuna...
And also, please stop saying that Yuna does not have a real 3F. You seemed to have ignored my comment earlier about how she had some problems with it until the 2009-2010 season when she managed to fix it. Her 3F is one of her best jumps and many people call it textbook quality.
