What does weapon accuracy score represent?

Im pretty new to EVE, and my brother asked me to PvP fit a thorax. I slapped some blasters and armor plates on that bad boy, and when I hover over my guns, it says "Weapon accuracy score: 74".

I have no idea what that means. Is this good? Is this bad? Will I be able to hit the broadside of a barn, or will I be better off ramming it?

It represents a swift reversion to 'Gallente Citizen 98230473082714'.



e. I would probably also like to know the answer to this Lol

Good question. Give me a couple years to get the muscle memory down and I'll let you know if 74 is a good number...maybe.

I would say it's f'ing fantastic; my Pally's tachs get more crit hits than normal hits and more normal hits than misses with only 3.4, so assuming that 74 must be God mode accurate, right? Then again, math was never my strongest subject, so there is that.

"----in' A, right?"

"Trouble is, those things cost like a million and a half each."

"----, you pay me half that and I'll hump in some c4 and blow the ---- out of it my own damn self."

It's tracking and signature mixed into one, according to google. I'm not entirely sure what exactly that number is supposed to tell me, except high is good and low is bad, I suppose. I'd say it's an attempt to simplify it, but I think it's actually more complicated. Tracking speed directly correlates with the targets angular velocity, so I can tell whether I can score a good hit or not, but I have no way of knowing whether a 70% "accuracy score" will hit a ship circling around me at 1.5 rad/s

Looking good with those glasses by the way, Bumble.

It's one of those changes where you have to ask if the devs who worked on this actually play EVE at all.

Put a ping pong ball in the toilet and aim for it.

That pretty much describes this games aiming mechanics.

Its not that the Dev's have never been hi-sec miners, more that if they ever admitted it they'd be designing new pattern's in the dust as they sweep the car park. Would you employ someone who spends all day mining in hi?

It represents CCP confusing the meanings of "simplification" and "obfuscation".

Man, I'd like to know what's up with this mystery number too. All I can tell is, the higher, the better. What are the thresholds? Accuracy score of 7 appears to be good enough for battleship vs battleship, but not for frigs, i.e., lots of misses on frigs.

We need an official CCP chart or graph or something. More info.

Looking at the chance to hit formula on Eve-Uni's wiki I'd guess that the weapon accuracy score = tracking for the weapons at a normalized 40km sig resolution.

It doesn't really remove any steps from figuring out relative steps to compare tracking with sig res to a targets angular velocity and sig so much as it introduces the 40km sig res constant.

Weapon accuracy score is your tracking in (rad/second) * 1000 normalized to a 40m sig.

So if your weapon score is 75 you can track a 40m frig at .075 radians per second.

If you are shooting at something larger, say a cruiser with a 150m sig, then you can track them at .075 * (150 / 40) radians per second.

Ty is correct.

If you want to know the to-hit probability against a particular ship, you need to know the ships sig radius and angular velocity, then normalize for a 40km sig radius (which I like to call the Ship Evasion Score.) When the WAS and SES are equal, your chance to hit is 50/50.

Unfortunately, the server doesn't tell your client the actual sig radius for anything other than your own ship, so you have to guess based on the ship's base sig, any TPs used against it, whether it has MWD on or not, whether it has any shield extenders, whether it has any command burst effects, and maybe some other factors I can't think of. Playing with the numbers on a spreadsheet or on a napkin, however, can give you a general idea of what various ships can get for their SES. Fast orbiting frigs get numbers in the 300s and 400s, cruisers are closer to 50s and 70s, battleships in single digits and teens, and capitals tend to be, hmm, something like 0.1 to 2 or -ish. Of course when two ships are stationary relative to each other, both their Ship Evasion Scores are zero.

Blimey, this looks more and more like work to me. I think that I will just close my eyes and hope for the best.

Question: Does this game appeal to accountants?Big smile

Are you sure about this. I thought that the sig of a weapons round affected the tracking irrespective of whether you are moving or not. If you fire a large round at a large stopped target you'll hit every time but firing a large round at a tiny stopped target you'll still often miss or graze.

Hey CPP - Time we put highsec back to how it was originally designed - http://i.imgur.com/GT0T0oS.jpg

Yes, I'm as sure as I can be on the assumption that the tracking formula is correct. The angular velocity is a multiplicative factor, so if that is zero the entire term is zero no matter what the other numbers (sig radius and WAS) are.

Of course, absolutely zero angular velocity just doesn't happen in EVE for the most part.

You can see the formula here http://wiki.eveuniversity.org/Turret_Damage .

Well, there's at least one advantages to the WAS that makes for less work - you can tell that, for example, a 0.1 rad/sec large gun is significantly less accurate than a 0.1 rad/sec medium gun.

Useful in the fitting window I guess, but not in the overview, where we're lacking a Ship Evasion Score stat and instead get the useless "Size" stat.

It's still rad/s values, but now it's related to unified 40km scan resolution, so comparing appropriate sized weapons to appropriately sized ships (or to be precise, angular velocity column in the overview) is bigger PITA now.
