Bink value also affects how bink works. If the value is negative, then it's auto-bink -- this is only for automatics, where the aim gets inaccurate as you fire at a rate proportional to the bink value. Semi-autos regard negative bink values as 0. If bink value is positive, regardless of what weapon type, the weapon won't bink as you fire but will bink when you are struck by a bullet, regardless of origin. Naturally, the higher the value the greater the inaccuracy and therefore the longer it takes to recover from bink.
