Pylon or Puck? (Zero Off Slalom Mapping)

[MatadorMaine]

Hit the button when gate hits GPS sensor  (puck) or at the pylon. 
Thanks.

Puck for slalom course.  Pylon for jump course.

[MatadorMaine]

Yes! That's what my research says...but seemed odd to me that it was different for jump/slalom.

@MISkier Is correct - puck for slalom, pylon for jump.

Don't know why,  it's just the way they set it up.

Mapping the course with the puck at the gates maintains a symmetric relationship of the pylon (skier) to the course in both directions. If the course were mapped at the pylon in one direction, then the pylon would be offset 2x the distance between the puck and pylon out of the course entering from the other direction. I don't know much about jump, but since it is run in one direction, it can be mapped at the pylon.
