So what you're saying is this does the same thing as gaming mouse UI. I can easily make a macro for my Theron gaming mouse that does the exact same thing, in fact I've done so.
Been pretty useless to try and use it in game. It doesn't reduce recoil having me "click" once every .25 ms. Doesn't increase my fire rate at all, since most weapons I'd use it on, are already automatic and can fire faster, and more accurately by me controlling my fire and not spraying everywhere.
Unless this is an actual hack that makes your automatic gun fire faster than the game's specifications, but I've seen nothing here that describes it as doing so. I'd call this less of a hack, and more of a macro that clicks for you.
