Speed is only a single factor in what happened. Reaction was the main factor. 

Every character pretty much reacted the same. Each one of them threw themselves into combat without a second thought. The only one of you that didn't was Rio. He watched his teammates moves and acted accordingly. In this situation Arwyn assumed that Arton would hold the monster back instead of destroy it. In a situation with where everything was going bad, Rio showed the perception to notice. And in this RP, everything can and will go bad. Luckily this time things worked out. From an outsiders perspective though, it looked perfectly coordinated
