made a comment in another thread that I thought warranted further discussion and didn’t want to hijack that thread, so here goes.

I've said this several times over the years, whenever Eric brings up partial credit, but for anyone new to the discussion:
If you want an accurate score, thresholding is bad.
Any time you force all-or-nothing, the score becomes unstable. This principal extends way beyond trick skiing into all forms of scoring metrics used to solve all sorts of real-world problems. "
Interesting idea. It was brought up in the context for partial credit for tricks, but if an accurate score is what we are after, for the sake of inclusion and fairness, let’s apply it to all 3 events:
For jump, the jumper would get full credit for his distance when he rides out a jump as normal, but would receive partial credit as follows:
- Lands on his skis but fails to ride away – 10% reduction
- Fall out the back - 20% reduction
- Falls out the back, but the helmet is the first thing to hit the water, 30% reduction
- Falls out the front – 50% reduction, but judges may award and additional 30% for “cringeworthiness” of the fall
For slalom, we currently have ¼, ½ and full buoys, but that doesn’t accurately score the skier relative to the others, so points will be awarded as follows:
- 1/8 point for crossing the wakes and skiing within 3 feet inside the next buoy
- ¼ as currently scored
- 3/8 if the skier hits the buoy and “has a yardsale”
- ½ as currently scored
- ¾ if the skier either gets back to the line of boat guides after the next set of boat guides, or begins his pull, but loses skiing position before reaching the line of boat guides
- 7/8 if he gets back to the line of boat guides, but loses the handle and doesn’t ski away
Ok, so hopefully we can agree that the above would indeed more “accurately score" each skier, but would be a judging nightmare and would do next to nothing to distinguish the better skier of that day.
The same can be said of partial credit for tricks. In the other thread, there were discussions about pre-turning, turning before getting in the air, holding a side-slide for 2m (an absurd criteria BTW). Just imaging the arguments and variations in “judging” if some form of partial credit is implemented and the long list of criteria it would involve. Remember that the judges have to call tricks in real time.
The bottom line is that there has to be some sort of “threshold” in any event to determine the score – even if you apply partial credit, what is the “threshold” for partial credit? The current trick scoring criteria is reasonably clear once you study it enough. The last thing we need is more subjectivity in judging. Partial credit would be an absolute nightmare.
