We've studied all WEF Grand Prix classes from 2020 and 2021. Here's what we learned about the most typical faults across all classes and by course designer!
Across all classes and CDs, the most faulted jump based on a combination of JUMP TYPE and JUMP DETAIL metrics was an Other Oxer (15%) followed by an Other Vertical (11%) ("other" means there was no special detail associated with it). In total, combinations represented 40% of all faults, with the most by a small margin delivered by a Vertical Combination-In.
