Outside of vats chance to hit is based on WHETHER OR NOT YOU ARE POINTING YOUR GUN AT THE TARGET. Perception has no effect outside of vats on combat nor does the majority of perks.

I understand I need to aim to hit! lol

try this, aim down barrel at an enemy's head at distance. pull trigger. Does every bullet hit their head? prolly not as that would be silly.

I was saying earlier that there is a "chance" to hit inside VATS and out. That is what I was asking for explanation.

I would think that the closer you are the better the chance. so at point blank, 60% is wrong as outside vats it is 95. therefore the perk got broken.

Bullet spread is mostly(entirely?) gone it was a weapon skill related effect. There is no such thing as a "chance to hit" outside of vats.

ok, so If that is correct, I see no point in VATS other than fun, slow-mo deaths! just put large scope on every gun and you got insta-kills!

There is a thing called Chance to Hit it's called percentages when aiming at body parts. Even when you're not in VATS there's still chances to hit

Point of VATS is to directly individual body parts more freely than you would normally.

It's working just fine for me. I was running a mod to fix this perk for a while prior to the patch, and I can verify that nothing has changed since then. It's giving me the correct 20% bonus. You're probably just going through an adjustment period while getting used to no longer having a (theoretical) minimum 2000% chance of successful headshots.

That's not how these are being added. There is a distinction.

You're not getting +20 to headshot chances. You are getting 20% -better- chances than the chance you already have. Suppose that your headshot chance is 75%. If your chances are 20% better than 75%, they are not going to be just 75%+20%=95%. Your chances are going to be 75%+.20(75%)=90%.

Thank you Curt.


I did some more experimenting last night and it seems to be pretty accurate. I had 1 instance of a few dozen where this happen again, I was aiming up a stairway and had a lower % on the head. My conclusion it was either elevation or a limb blocking the view.

If you read my post you'd clearly see i'm adding percentages which increases it's odds but you don't get the 70% you get 60% like how someone thought you would.

I was actually using math to say you're not adding 50+20 you're adding percentages. 50% + 20% is 0.6 which when rounded to a percentage is 60%

Which means 20% just adds a few points into it. Of course as I said it's not foolproof but that's the basis on how these percentages work on a calculator. The game may give off less of an increase.

I am not certain how you arrived at this.

edit:

did you mean...

50 + (.20)50

50 + 10

60

Then this is correct, and is the same as QuantumCurt's explanation, I believe.

It`s for balance.


Start using VATS enhanced scoped rifle with sniper perk.


You will see 95% on all body parts easily at long range.

All I know is before I got macreadys perk my headshot chances in vats were around 80% at a decent distance as long as the enemy was facing me and there were no obstructions. After the perk it was 95% no matter what which was fun for a sec and got old quick. after the patch my head shot chances in vats are rarely above 65%-70%... even at point blank range when all other limbs and torso are at 95% so something is wrong. I just don't use vats for headshots now but still I had better chances prior to getting macreadys perk, I wish I never got it..

50% + 20% of 50% is 60, but 50% = .50 and 20% = .20 added = .70 = 70%. I'm not arguing your point, just pointing out that standard addition, even addition of percentages is still addition. Nowhere is 5+2, 6. It's 7.

I only wish that they had clearly stated that the bonus was 20% of the base percentage to hit, not 20% bonus. I admit that, in the long run, it means nothing. Sure it was fun having 95% hit chance on a headshot, always, but now it's always much, much lower. Arms, legs and torso's are still 95% so I guess it really doesn't matter. Just less headless corpses. If I want to hit their head I just snipe using my scope. That, at least works.

I'm not even gonna try to sugar coat it...this made no sense.

50%+20%=70%. It most definitely does not equal 60%, regardless of any "rounding" or anything like that.

20% better chances means exactly what I said. Your chance would be equal to the base chance, plus an additional 20% OF your base chance, e.g. if your base chance would be 50%, your modified chance is 50%+.20(50%)=60%. This is exactly (not basically) what the in-game calculator is doing.

Not trying to "pull authority" here or anything like that, but I'm a physicist with dual undergraduate degrees in physics and mathematics. I know how to calculate percentages.

The only possibility here is that we're unclear on the wording, but I don't think that's the case. There are other perks that specifically apply +10% to damage, and there are also perks that give you 10% better damage. The first is additive. The second is multiplicative. For example, Bloody Mess gives you +10% damage, while Gun Nut gives you 1.5x (50% more) damage from ballistics weapons.. Killshot is worded like the latter, it says that it's giving you 20% better chances. Thus, your actual percentage chance is x+.20x, where x is just your base percentage chance.

I'll just say either you guys are mistaken or how the calculator adds percentages are incorrect. I was using this to add them but it just changes the answer to 0.6 which equals to 60% http://www.online-calculator.com/

What exactly are you entering into the calculator? I'm not wrong, unless my entire interpretation of the perk is incorrect, which I don't believe to be the case.

Percentages can be added in different ways. There are 10 apples. I have 4, and you have 6. That means I have 40% and you have 60%. If you give me two apples, you are giving me 20% of the total number of apples. That means that I now have 40%+20%=60% of the apples.

If I have 40% of the apples and you have 60% of the apples, and you give me 20% of YOUR apples, you are not going to be giving me 2 apples. You're going to be giving me .2(6 apples)=1.2 apples.

I'm putting in exactly: 50% + 20% and it just gives me 0.6, which rounded to a percentage is 60%

I'm not sure why it does this but as I said either the calculator is doing something wrong OR you guys are incorrect.

Not once did I claim my comments regarding them was foolproof in fact i've stated 3 times "it's not 100% foolproof and I could be wrong" i just know what the thing was giving me back as an answer. We need more proof with PC players using hard data to suggest how the % calculations are being done.

The TC was complaining that the game should be adding the 50% + 20% to 70% yet he was getting back 59% or something in VATS on the head. Someone before me stated it's really more like 60%, which was this post here

The issue now becomes: the percentages being added is not in the normal sense. The MacCready Killshot just adds it differently than normal so it's not the same as the example the previous poster was saying with apples.

I think I may understand what you are doing.

Were your key presses on the calculator like this? (key presses separated by commas).

5,0,%,+,2,0,%,=

If so, this is your mistake. While it is true when considering a whole, that 50% of a whole added to 20% of a whole results in 70% of a whole, this is not what is taking place with this perk.

Percentages for the topic under discussion are correctly calculated as QuantumCurt has outlined. My BA is in mathematics (former math teacher).

Not jumping on you, just flapping my old teacher gums a bit. ;P

I dunno. I tested last night.

shooting at a wall while aiming = slight deviations.

aiming at distant object = greater deviations (as you would think)

aiming at distant enemy's head = kill shot almost every time!

with vats, I seem to have even greater variations in accuracy.

I'm done with it.

Guys, this math question is spelled out in the wiki. I don't remember the answer off the top of my head, but it's there.

And QuantumCurt, I understand where you're coming from, but this would not be the first time the game does calculations in a non-logical way. Damage increases with Ninja, Bloody Mess, Sneak, etc also don't follow what math people would consider standard methodology - in fact they don't even arrive at the same result depending on the order you get the perks, which is just plain wacko! But it is the way it is.

Excellent! Makes perfect sense now. Is it not surprising how a single word can make such a difference? Additional vs. Better. Amazing.

Thank you.

Have calculators actually gotten to the point where they've made it so simple that a person doesn't actually know that 50% = .50 and 20% equals .20? If so, that's sad. I use my adding machine at the office all the time and there is no adding of % function. The only % function on my calculator is for the result.

StealthBlade must be a troll everything he says on here is a lie.

Like I said, it's the 3 guys rent a hotel joke. Basically when the way the joke is told gives a false perception on the way you'd calculate your answer. But if you crunch the numbers in the proper mathematical procedure (there's only one right way to math) you'll get the right answer. The bell boy is a thief, fire his ass.


So what I'm gathering is Beth went the way of the bellboy, and is not using the correct formula.

Here we go again...

It would appear that the answer is 70%. Also, you could grab a calculator and check for yourself: https://farm2.staticflickr.com/1652/24936275966_d211e12435_o.png
