the only stunt matter

There is no checkpoints, you only have to perform one stunt, isn't it?

But it's not easy, you need to earn more than 9500 points to earn bronze medal, and that is already more than doing a PF on this map entirely (9475)

Silver require 9800, Gold require 10100, and that's 5 figures already.

The ultimate object is to tie or beat by Personal Best which is 10375.
