I have told myself not to "complain", but what is the meaning of 0 drop if I-Ling out of 12 runs? Statistically (although number of trials is not large) it is at most 8.33%, without taking so-called x1.5 drop rate into account. I am not going to unlock her hippos, but just want to get 6 copies (including the "free" 3 copies) for album. By simple calculation I have to run at least 39 runs (27 more... and assuming 100% successful).

Now I remember 2 statements from other users:

1) 1% drop rate will only become 1.5% even under x1.5 (very good description and explanation)

2) this long 14-day already implies a low drop rate

So true!!! v_v
