Hi, I was wondering if Dash vaults are really Parkour.

Everytime I see a dash vault it seems to me that another vault (Kong, Regular, lazy etc) or simply jumping over the obstacle would be more effective than a Dash vault.

I may be wrong but I was hoping that someone could give me a situation where a dash vault would be the most effective way to pass a obstacle.

A useful time I've seen and used a Dash Vault is when jumping over a few obstacles [say about 7 feet long and 4 feet high] and instead of landing and running, where you could lose balance, the hand placement gives you back the balance and lines your legs back up for the run.
