What is your overall small arms accuracy?

Re: What is your overall small arms accuracy?

K, I excluded the AT, Defib, Explosives, GL, HG, Knife.

Leaving only AR, Carbines, LMG, Pistol, Shotgun, Sniper Rifle, and Sub machine gun (in my mind these are all “small arms”)

77523
47865
43236
17215
9540
4783
12638
= 212,800 TOTAL SHOTS FIRED

Total shots HIT with black weapons
15129
11339
6597
3722
909
1961
2081
= 41,738

overall small arms accuracy = 41,738(Total Shots hit)/212,800(Total shots fired) = 19.6%

Your math would be to add the percentages for each weapon…
20
24
15
22
10
41
16
and divide by the number of small arms, in this case being 7. Giving you….
21.14 %

Which is incorrect

Re: What is your overall small arms accuracy?

If you add the totals, excluding AT rocket and GL and divide by 11, that'll give your average.
I could be wrong, I hav'nt had to do this kind of math for over 18 years.
Grenades too, take those out.
and knife AND Defib, which'll screw my 33% to around 7% :cry:

That is completely wrong man. I don't understand you guys think you can add percentages and then divide them by the total number of percentages.... It doesn't work that way. If you were to use carbines once and Assault all the time, those two percentages are WEIGHTED differently.

But your math doesn't weight them differently either. It just says "a bullet fired is a bullet fired" and it's completely insensitive to the individual accuracy of the gun used, and the time it has been used. Nor does it consider that carbines are, on the whole, more accurate than LMGs.

Neither calculation is perfect, but I prefer the one at bf2players because it factors in the fact (at least partially) that someone might be exceptional with a few guns and mediocre with the rest.

OMG dude you're missing the point. You CANNOT add two percentages and divide by two to get an accurate overall percentage.

Does anyone here other than me know how to do basic math? HELP ME!!!!

The POINT of "overall small arms accuracy" is that a bullet fired is a bullet fired.

36.59%

By the way, BF2S calculates its accuracy wrong. Remember to add up all of your small arms percentages and then divide by the number of values - in this case, 13.

Rubbish. No one else is going by your method, so use the BF2S percentage like everyone else.

This makes you 27.57% (after the D point, anything over 50 is rounded up, so your really 28% )

Re: What is your overall small arms accuracy?

For me, I am currently at 19.21%. This sin't bad when you consider that 1 month ago, it was at 16%, and I had 300 hours booked at that time. Now 1 month and 100 hours later it is up. When i first started, it was like at 9 %

Hi, Dominic. I'm not entirely sure what kind of problem you are 
referring to. Certainly there are at least some situations where you 
can average percentages. For example, if there are 50 questions on an 
exam, and three students got 20%, 30%, and 40% of them right, then the 
average number of questions they got right is 30%, or 15 questions.

I suspect what you are thinking of is cases where the percentages are 
taken from different totals, in which case weighted averaging is 
needed. For example, if I survey 20% of 50 people, and 80% of 500 other 
people, then I have not surveyed (20+80)/2 = 50% of the total 
population, but:

   .20 * 50 + .80 * 500   10 + 400   410
   -------------------- = -------- = --- = 74.5%
         50 + 500           550      550

The problem is simply that the percentages in such a problem do not 
represent fractions of the same total, so they can't be added.

I get what you're saying, but your calculation is still wrong. And so is mine.

I'll change it for you.

Re: What is your overall small arms accuracy?

I get yer.
If I had a crappy 10% with Assault rifles and I shot 1 person with a Sniper I'd have a 55% accuracy, which is bollocks.
But then looking at the stats on a page is accuracy based on kills.
I can shoot people all day with the L96 and only take them down to 2 bars.
It counts kills, not bullet hits.
Therefore, the accuracy on the stats is worthless, and so is this entire thread.
Now I can wait for Lugal to tell me I'm right n get a sweetie ?
I could of course be wrong, and I'm not getting at the OP, it was a good thread, it's EA's fault for misleading people by calling it an accuracy score, when it's another K/D ratio.

If you read what your professor is saying... He is saying the exact same thing I was. Because percentages are taken from different totals, you cannot add percentages and divide.

Regardless of what you said, your math is just as flawed.

And that is from a 5-second Google search - he's no professor of mine.

Accuracy on bf2s and other stats sites are actually taken from the shots fired/shots hit, so they are accurate readings.

And YES thank you for backing me up!

Re: What is your overall small arms accuracy?

well according to bf2player my accuracy is actually 26%, whew

The fact that you had to google it is testament to your math skillz

No they are not. Didn't you read the thing I just posted? When percentages are drawn from different totals, they cannot be averaged. Just the same, you can't lump all of the totals together since they come from different, distinct samples.
