Actually,

the mid-back sections (behind the white signs) ended up being 15 and 16. The floor setup was different than what the website said it would be. 10 is somewhere in the middle if I recall. But I was in 15 night 2, which is further back than you'll be and it was AMAZING! Eventhough I'm only 5'2" and I was seated behinda giant couple, I still had a great view and the energy was contagious.
