So. Castrum Meridianum. Final boss, cannon phase. Most people insist everyone fire at the same time, and freak out because every single time it fails.

"How tough is it to follow a countdown?" Well, it is a bit tough if people don't set a standard on how countdowns work. As far as I see it, there's at least 3 different options:

- A person says "3,2,1" and you are expected to fire at the moment they SAY "FIRE!"
- A person says "3,2,1,FIRE!" AFTER which you are expected to fire.
- A person says "3,2" and then you are expected to fire when you assume the "1" is arriving, without anyone even planning to say "FIRE!"

I have had all 3 of these happen.

So, set a standard, or tell your countdown method beforehand, mkay?
