Can I repeat jumps in Stunt Run and still get points for it?

Here are the rules for repetition:

1. The same jump is only scored once. This means if you go over a jump in one direction and do a flat spin then go back and do a barrel roll in the same direction you will not be scored for the second time.
2. Billboards and smashes can not be repeated.
3. Repetition is per combo so you can go back and try again if you crash.
4. Boost scoring degrades over time. It ends up on 1 point a second.
