Flyff - Drop Rate Probability Theory

Drop Rate Probability Theory

Usually drop

Verification result

When just this you see, as for denominator you think that you are not almost wrong with 2.5G.
As for the fortune circle once there is an effect, we would like to see, is. One tenth it has risen.
The fact that error is large to "?????????" of the expectation where error is most difficult to appear is puzzle, but.

QUEST drop

"Feather from small ????? acquisition ratio of eye bat"

Lv15 1310/2000 0.655
Lv15 333/ 500 0.666 (fortune circle)
Lv15 399/ 600 0.665 (only white name)

Theoretical value

1,500,000,000/2,000,000,000 0.75
1,500,000,000/2,500,000,000 0.6
1,500,000,000/3,000,000,000 0.5

Denominator 2.5G is closest, is, but one tenth it has become raising.
The fortune circle seems that is not the effect in the QUEST item.

"Root from 2 classes ?????? acquisition ratio of white ???"

Lv45 145/ 200 0.725
Lv60 77 100 0.77
Total 222/ 300 0.74

Theoretical value

2,000,000,000/2,000,000,000 1.0
2,000,000,000/2,500,000,000 0.8
2,000,000,000/3,000,000,000 0.666

The numbers of verifications are few, is, but this has become conversely lower than denominator 2.5G.

Summary

Fortune as for the circle usually properly there is an effect in drop.
Fortune as for the circle there is no effect in QUEST drop.
