Who decides how long the "wait" is? You check 6 somebody and in 5 seconds they need another check 6 but because, not only you, but four other people gave a check 6 call, your 2nd, needed 6-call doesn't go because the game thinks it's just another call from the first time.
Does that make sense?
This isn't chess, it's air combat........... One half second too early, you don't quite kill it, one half second too late and you don't quite live........... The game is a series of moments, not minutes.
