When I'm standing, after having done nothing I can only hold my breath to steady my aim (Right Mouse Button) for about 7 seconds. Then the aim goes all over the place, process repeats. Unrealistic.
From a rest i could hold my breath for a minute or more before shaking any day. After running HEAVILY 7 seconds makes sense to me. Please do a couple of shuttle runs in real life/ hold your breath while holding a yardstick or something to make this more realistic. Thanks guys
