A 10th of a Point

In Olympic style commentating, here goes The Jump:

Commentator 1:  Next up, Cullen.  He's been very successful with these jumps all season, Ellie.
Commentator 2:  Yes, I know, Mike.  Let's see how he does.  The crowd is now waiting...
Commentator 1:  Oh!  So, close.  If only, he'd stuck that landing Ellie, that could have been a perfect 10!
                           But that hop's going to cost him a 10th of a point.
Commentator 2:  Oh I know, Mike.  But, he's a baby, so he's happy with it.
