78% is the chance to get a 0.1% drop after 1500 runs. It's a mathematical fact. I said it would take 3000 runs to have a 95% probability of obtaining the item at 0.1% drop rate. This is also a mathematical fact.
You can learn the math yourself here.
With the amount people spam Qilin, if it were much higher than that, we'd be seeing a lot more Coruscantis. Especially considering every run is 18 chances at a drop.
Fact of the matter is, even with mass Qilin spamming, Coruscanti remains rare, and every other trashy THF on every server has a Mandau.

Those were the dumbest posts I've read since Rosina stopped posting.
Lux Pugio doesn't even remotely compare to Mandau, and you probably shouldn't be using Evisceration outside Abyssea on Thief anymore. Also, you're really underestimating the effects of that +35 Attack. Go merit Exenterator and think about what you've done.
By the way, if it were a 1% drop like you think it would be after "normalizing the ODDS" you'd see a Coruscanti on average, once every 17 Qilins to someone in your alliance.
0.99 ^ x = 0.05
x ~= 298
298 / 18 = 16.6
It's not a 1% drop. It's at best 0.2%.
Just for you, and hope you get off my TOE.
1-(1-%Chance)^Repeat = Real % chance over time.
10% chance over Repeat = this
First try
1-(1-(10/100)) ^ 1 = 10% chance you get it.
Second try
1-(1-(10/100)) ^ 2 = 19% chance you get it.
3rd try
1-(1-(10/100)) ^ 3 = 27.1% chance you get it.
10th try
1-(1-(10/100)) ^ 10 = 65.13% chance you get it
Now let talk about .1% chance, with your number.
1000th Try
1-(1-(1/1000))^1000 = 63.23% chance you get it
*Edit: Just so i include 1,500 to make you happy about your 78%, but i corrected your imprecision.
1500th Try
1-(1-(1/1000))^1500 = 77.7037236297098% chance you get it
2000th Try
1-(1-(1/1000))^2000 = 86.48% chance you get it
3000th Try
1-(1-(1/1000))^3000 = 95.028% chance you get it
And Now let talk about 1% chance.
100th Try
1-(1-(1/100))^100 = 63.39% Chance you get it.
200th Try
1-(1-(1/100))^200 = 86.60% Chance you get it.
300th Try
1-(1-(1/100))^300 = 95.09% Chance you get it.
Do my math and number make sense, hell yes it do, and ive been posting this 1yr ago on FFXIAH.COM
I know 2 guy that spam Qilin with me, that got ~1/50 and other one got ~1/90, and just from that part, it can be either they REALLY lucky, or the proposed .1% is bullshit. IS the whole reason i say don't bring your spagatti math, as the base % is totally unconfirmed and people just tend to cry "i am 0/9,000, when in fact they are just 0/35"
I can agree more on that one, as i saw 2 Coruscanti over 90+ run, and if apply my math or your math, then it give same result:
18 player * 90 = 1620
1-(1-(2/1000))^1620 = 96.0962959473256%
1500th
1-(1-(2/1000))^1500 = 95.0362267868937%
Anyway my initial point was saying: You will get Coruscanti by trying finish twastar.

The only "same thing" happening here and on FFXIAH is how my English stink, i try hard at least, but people tend to think i am ignorant just because of that factor, and nor you or anyone will make me stop posting, so why loosing your time with that?
You know as many i am French Canadian, and i try hard at least to write post in English.
That ~1/50 is actually ~1/900 and the ~1/90 is 1/1620 (unless someone else in the alliance got it during that time - if these were both together the best we can say is 1/810)
Currently, "reported" is 1/768 drop rate for Coruscanti from Qilin (this is pretty close to the 1/810 from above). That's not enough to know exactly the drop rate, but if the drop rate were 1%, the probability of 1/768 happening is so minute it's not even worth discussing. It points to a much lower drop rate (0.1-0.2%).
At a 0.1% drop rate, you'll see a Coruscanti, on average, to someone in your alliance, once every 167 Qilins. At 0.2%, you'll see it on average once every 83 Qilins.
This isn't spaghetti math. It's simple probability theory.
And I don't care that you're French-Canadian. Tu parles Anglais comme une vache espagnole. That said, I doubt you could express yourself intelligently in French, either. If you can't express yourself intelligently in English on the English forums, go muck up the French forums where I'm the only one who has to read your dribble, and save everyone else their sanity.

I haven't laughed this hard at a thread here in a while. People came in to express concern about a piece of gear they think is bugged and it got derailed. Not like a purple monkey dishwasher in 2-3 pages but in 1 fucking post.
