First of all, he only lost by 0.67 points, so it was close.
1)He did not have much variety in his grabs, unlike tanner.
2)He didn't hit the starilizer rail, which tanner bettered him with a nosepress.
3)His spins in the middle part of the course didn't have as much style as Tanners.
Olenick's score was closer to tanner's than people think which was because of his rail skills.
However, Jon's run deserved a higher score, but that's another story.
