Two-Thirds or One-Half?

Hi! My name is Emily, and I've been working on the hourglass sweater for the Knitting Olympics too. I didn't finish it, but got pretty far:


So my question to you is, do you think I'm 2/3 of the way finished? Or more like 1/2 way? Because if I'm 2/3 finished then I will qualify for a silver metal. Either way I love this sweater and can't wait to wear it. Thanks for all of your discussions of the pattern on this blog. They have been helpful.
