Robert's Skateboarding Law

When skateboarding, before performing a trick, if your board is pointing in a certain direction and you have a certain foot forward (initial stance), you can perform the same trick two times in a row, and after landing the second trick (final stance), your board will be pointing in the same direction and you will have the same foot forward as before you started the first trick.

This law holds true whether the second trick is performed exactly the same as the first, in switchstance or in fakie.

Therefore: Assuming Trick 1 = Trick 2, given an initial stance, an intermediate stance and a final stance:
Initial stance = Final stance


Further Assumptions:
- A wheelie (tail or nose) does not constitute a landed trick
- This must be performed while street skating (continuously going in the same direction). If this is performed on a halfpipe it still holds true if each trick is performed at each end of the halfpipe with no tricks in between.


Example A:
Initial Stance: Nose pointed forward, left foot forward (regular stance)
Trick 1: ~360 varial kickflip is performed~
Intermediate stance: Nose pointed forward, left foot forward (regular stance)
Trick 2: ~360 varial kickflip is performed~
Final stance: Nose pointed forward, left foot forward (regular stance)


Example B:
Initial Stance: Nose pointed forward, right foot forward (goofy stance)
Trick 1: ~Backside kickflip 180 is performed~
Intermediate stance: Tail pointed forward, left foot forward
Trick 2: ~Backside kickflip 180 is performed~ (fakie or switchstance)
Final stance: Nose pointed forward, right foot forward (goofy stance)


Example C:
Initial Stance: Tail pointed forward, right foot forward
Trick 1: ~Backside 180 varial heelflip 360 is performed~ (The body moves 180 degrees, while the board 360)
Intermediate stance: Tail pointed forward, left foot forward
Trick 2: ~Backside 180 varial heelflip 360 is performed~ (fakie or switchstance)
Final stance: Tail pointed forward, right foot forward
