EVE New Citizens Q&A

I am not sure how this works out to 56%...

Base station reprocessing rate = 50%

Station tax = 5%

Brings it down to 45%

My reprocessing skill is 4 = +12%

Brings it to 57% total

My reprocessing efficiency is 1 = +2%

Brings it to 59% total

My veldspaar processing is 1 = +2% (and yes I am selecting the correct mineral stack)

Brings it to 61% total.

So why does the station only say I am getting 56%?

What am I leaving out of the calculation or not understanding?

ok I raised my veldspaar processing to level 2, which should add 2% making it total of 58% but it's only 57.1%

Why is this not adding up?

Base station reprocessing rate is 50%
Reprocessing 4 gives a 12% modification (50*1.12)=56%
Reprocessing efficiency 1 gives a 2% modification (56*1.02)=57.12%
Veldspar processing 1 gives a 2% modification (57.12*1.02)=58.26%
Station tax = -5% (58.26*0.95)=55.35% reprocessing yield

There are always slight discrepancies (as in tenths of a %), especially when reprocessing multiple items; because the exact formula is used to calculate the number of minerals you receive for each type. This is then rounded to whole numbers, as you cannot get half a tritanium, and presented as your yield.

With reference to your second question 5% of 30 is 1.5 (30*0.05), 30-1.5=28.5%

^^ You appear to have missed the bit where the OP was mistakenly assuming that a percentage increase or decrease of another percentage was related to the 100% figure to guesstimate their yield, both answers given by the 2 posters you suggest need a new calculator are mathematically correct as per the formula given by CCP and the rounding that they employ.

This thread is the reason I just shoot things, be it ships or rocks

I love it when ppl try hard and fail. Also please do tell us how the order of calculation affects anything at all when we're doing multiplication.

I did not miss anything, see section quoted below.
50 + 2% IS 51 not 52 as this poster clearly states and so he needs a new calculator or to go back to math class.


When working with percentages one can add or subtract 2% which is a slightly more complex set of formula because you have to first calculate what that 2% is before you can add it to or subtrract it from the base amount. Multiplication by 1.02 or division by 0.98 simplifies the math. But in the end they will always give you idnetical results.

You are however correct in regards to Jonah Gravenstein, reviewing his post I see that I incorrectly included him in my comment and so I apologize to him for that.

Your contention was that I missed the part about how to apply percentages in EvE and that is YOU interpreting something tinto my post that is not there simply because it suits YOUR reasons. My comment was strictly about the actual math involved and if you had used a calculator you would have seen it as clearly as I did.

Later in my post I clearly stated that CCP applies these things in a very specific order and it was likely that not understanding that order was a possible explanation for the discrepancies noted by the OP. While not correct in the strictest technical sense it is correct from a basic view point. I also see that you are choosing to ignore the fact that I referred the OP to sources that contain the information needed to solve the noted discrepancies because I lack the knowledge to fully describe them.


Never stated that order did matter when it comes to basic multiplication, but it does when you are trying to follow CCP's crazy logic.
As a simplified version if we start with a base value of 50 and then add 2 bonuses that are 2% each we can come up with different end results depending on what order you apply those two 2% bonuses.
50 * 1.04 = 52.
50 * 1.02 * 1.02 = 52.02.
Both are mathematically correct and both are correct in EvE depending on how and where they are applied.

And let's not even get into the complexity of varying percentage boosts and how those combined with stacking penalties place a huge emphasis on the order in which we apply simple multiplication to the world of EvE.

And you call me a silly man. Taken as a whole the statement as you re-posted it is incorrect because half of the math is incorrect and therefor the conclusion drawn in the statement is incorrect.

Breaking this statement down into it's 2 component mathematical parts I want to deal with the second half first and that is
50 * 1.02 = 51
This is correct so we can ignore it for this post.

May I humbly suggest that you get a calculator you may need it to follow the highly complex math that follows.

So that brings us to the first mathematical part of the statement which is incorrect.
50 + 2% = 52

To solve this we first need to determine what 2% of 50 actually is.
There are several methods we can use to do this.

The first method is to divide 50 by 100 and come up with 0.5.
Now that we know that 0.5 is 1% of 50 is we can simply add 0.5 + 0.5 to come up with 1.

Another option is to convert our 2% to it's decimal equivalent by dividing it by 100 and coming up with 0.02.
Now we can multiply 50 * 0.02 and the answer is 1.

Either way we do this we have determined that 2% of 50 is 1, not 2 as Tiberius Heth claimed.

Having firmly and accurately established that 2% of 50 is 1 we can then return to the first half of the math you quoted and we can clearly see that it is wrong.
It was stated that
50 + 2% = 52.
When we know the answer is
50 + 2% = 51.

not

adverb \ˈnät\

. used to form the negative of modal verbs (such as “should” and “could”) and auxiliary verbs (such as “do” and “have”) example: 'it's not 52'

. used with a negative word to make a positive statement example: 'Tiberius is not wrong'

. used humorously at the end of a positive statement to show that you really meant the opposite example: Donnachadh is a math whiz... not!
