Handspring full on, pike
The handspring full on with a pike off does exist in the code of points, but that’s about all I can tell you. Who has ever or would ever do this vault…unclear. It does have an exceptionally high D score, and is one of the very few vaults that has increased in difficulty in the most recent code update when nearly every other vault was decreased to try to bring vault more into line with the other events. It’s a testament to just how under-valued this vault has been for the fact that it’s insane.
