How is accuracy working in BF4?

Hi there!

I was reading lots of articles and threads in different forums, but i can't get it.
How is the accuracy working? How is it different from the stability stat (recoil)?
Aren't they connected to each other?
And so, is it true that not all of bullets hit a target, even when i'm shooting a full-auto, controlling the recoil in 100% and my crosshair is right on the target?

Yeah, I know. A lot of questions. But I'll be really thankful to someone who will explain it for me. :-)

You make a question that has been developed in dozens of threads.

Accuracy: Capacity to hit a given target with one bullet (or a set of them) aiming perfectly.

It can be measured as the difference between the desired effect and the achieved effect . In cm at a certain distance or better in degrees (or radians) regardless of distance.

There are two causes of inaccuracy:

- Spread: deflection of point of impact with respect to aiming point. This is random up to a certain spread for every bullet in the burst, which in the model BF4 grows with each bullet up to a maximum value. This means that even shooting a single bullet aiming perfectly there will be a random deflection (on weapons that have spread).

- Vertical and horizontal Recoil: it moves the aiming point cumulatively with each bullet if the Recoil is not corrected. They are also random within certain values.

The final position of hit is the result of combination of both causes. And the position is random (but bounded).

As this is difficult to analyze analytically (but not impossible) we use to analyze by simulation (hitrate, symplot, etc ...) firing thousands of bursts against the target (in my calculator 10,000 bursts) to obtain the statistical parameters that may define the accuracy ( number of impacts / number of bullets fired, number of bursts reaching damage 100/ total bursts, total achieved damage/ total posible or other ). That varies with distance.

You can see qualitatively the combined effect of recoil and spread in:

Incidentally, the Battlelog weapon stats you mentioned should be disregarded completely. They are misleading and confusing.

"you obviously don't know what an argument is as there is only one person battling. Do you really fucking think I want subs? You think you can act all big and powerful just because you sit on a computer at least 6 hours a day like the probably nerdy unwanted retard you are with 4.3k subs? You think 4.3k subs is a lot? LOL you need medicine man. I don't want any subs as i just have a google account for other media and writing comments. Think twice before you act. You even said in your video you aren't that great of a player, and the comments agree you aren't. Maybe you should once again think twice before you act, stop being such an annoying, ignorant bastard that everyone wants to shut up, and god, literally, just shut up. Your voice gave me a headache :s"

"As a youtuber shouldn't be trying to be reeling in your viewers with exciting stuff being said not your boring ass commentary for your video"

"The more you watch his vid the dumber he gets I swear he's borderline autistic look I got shot behind cover beacuase thin sheets metal are unpenetrable. Bf4 is just as quiet and tactical as bf3 random explosion in the background . Player has dissconected from chat
You started playing bf3 and never touched bfc1/2. Please do yourself a favor and shutdown your generic cod channel down"

"Nice clickb8 Faggot w8ting for your shit tier video to disable comments . Fucking newfag cancer go play some cod you activisiom cock faggot"

"I don't see why he [MarbleDuck] always tries to shit on levelcap he is better and has a million more subs...and also "there isnt a best gun in she game there are guns that are better that others at different engagement distances" yes thats true and whichever is the best/most average at all of them is the "best gun""

"Marbleduck you don't know shit lol levelcap knows more than you do you cant talk about how someone puts up garbage when you do yourself your a newcomer to YouTube acting like you know shit step up in the food chain first then you have the right to talk otherwise your just a fish trying to compete with sharks"

"Why don't we just witness "LevelCap vs MarbleDuck" One on One both on Battlefield 3 and Battlefield 4 seen as there is so much Controversy about the Two Youtubers"

"stfu cunt, BF3 was way better end of discussion"

"Stfu man, you're be littleing the most looked upon Battlefield Youtuber. No one cares about you, how much of an ego you have, or quite frankly your opinion. It's a fucking game.... Does it really fucking matter? Pathetic man."

"fuck you asshole, dont talk shit about total"

"Wtf is your problem? You have no subs and he has millions, yet you pick on him like some kind of stubborn, ignorant, rude child born with a silver spoon is his mouth. It's easy to do that, for example... You said there was no background noise yet there is. You say you're a fairly good player, you're not."
