gear being additive is consistent with the rules for EXP. the gear bonus is a small little thing added on after you get all the familiar cards and buffs and event boosts.
I remember it was this way for a long time. first noticed it grinding at the lion king place when it was party play. the pendant bonus was very lame, tiny and it doesn't even multiply with party bonus...
I had always assumed they would run by the same rules.
I might review my stats courses if I had time...
also check your honour stats, i got bonus drop for one of mine
EDIT 3
wow I have remembered more stats.
standard deviation of the number of drops based on 0.04 chance of drop (1/25)
is 6.5
Standard dev table for each multiple of drop rate, based on a basic drop rate of 1/25, 1100 monsters
(OK i know this is prob not right method, but i forgot how to to do properly and this will do for now until a stats expert comes in)
take diff between the mean you get from test and the expected value based on your hypothesis, divide by standard deviation. get Z score.
Z = (average of tests - expected average) / (standard dev / sqrt of number of tests you do)
http://en.wikipedia.org/wiki/Standard_normal_table
get probability there from your Z score ( use cumulative table) higher your value, higher chance your hypothesis is wrong.
in stats usually go for 0.95. if it is greater than 0.95 hypothesis is wrong
0.95 corresponds fo Z score of 1.96
basically if your Z score more than 1.96, your hypothesis is wrong. if not you cannot reject it
so suppose you thought drop rate is 3.0 and you did tests and Z score turns out to be 1. the result seems off like 10 from what you exoect or so but you cannot conclusively say that the drop rate is not 3.0.
it might still be 3.0 and you need more tests
EDIT 4 - more explanation - for example
so you might think like is greed pendant additive or mult with 2x drop
so here, you test two hypotheses with 2.2 and 2.4.
if you can reject 2.2 and not 2.4, then you can prob say it is 2.4
if you cannot reject either then it may still be either of them and more tests needed.
ANOTHER EDIT
I will redo it for this data pack
(ok when i first did it i forgot formula)
Z score is 4.5/(8.11/sqrt10) = 1.75
P value is 0.92
8% chance of more further from what you expect.
so there is an 8% chance of a more extreme result.
so it is just within the 95% threshold. so it depends on what threshold you think is right. in psychology, climate studies and otherr fluffy subjects they lower threshold to 90% or lower so their papers contain "results"
but since it is within 95%, I would say you cannot reject the hypothesis that drop rate is 1.6. So the drop rate is 1.6, until you do more tests
back some time ago, me and guild collected data on the trait boost potion. it was also on the edge of the threshold, but just inside - haha nexon RNG is a bit iffy at times.

SaptaZapta Wrote:Today's runs were with pig only.
Results: 61, 58, 72, 70, 74, 54, 74, 60, 64, 72.
For an average of 65.9, which is only 1.5x my average with no drop buffs.
This can mean one of three things:
1) Mutant Ribbon Pig familiar is only 1.5x drop, not 1.6x as we have always thought.
2) I have a 20% drop buff somewhere. That would also explain why the Greed pendant is only giving me ~15% instead of 20, and why Straatlamp's 3x drop was only 2.8x my "base". But I have checked all my gear, skills, link skill, character cards, monster life, inner ability, and can't find anything that would do this. If I do have this mysterious buff, it is additive with both the pendant and the familiar.
3) RNG is messing with me. Need more data.
Z score is 4.5/(8.11/sqrt10) = 1.75
P value is 0.92
8% chance of more further from what you expect.
so there is an 8% chance of a more extreme result.
