If you want to add to your result, just spent 50K, got 2 Bianca Tulip out of it.

* 9 (1.8%)
** 470 (94%)
*** 19 (3.8%)
**** 2 (0.4%)

After 50855 seeds i got 0(aka nothing) 4* girl =D.

I wonder if i can get a 6* girl in premium gacha.

Another 50K, got a Cepha Lanthera this time

* 7
** 462
*** 30
**** 1

Here I will drop this for future references..
Note that the draw is doing in 1 batch not total

510 roll (51k Seeds)
1* - 19
2* - 469
3* - 22
4* - 0
5* (ampys) - 0

1000 roll (100k Seeds)
1* - 20
2* - 930
3* - 50
4* - 0
5* (ampys) - 0

You guys have way better luck than I do. I haven't had pulled a single 4*.

Just wanted to throw this out there. Didn't know it was possible, but I just pulled a Sacred Beast DEF ampy out of free gacha.

This made me rofl pretty hard, I'm teary eyed here.
I feel your pain, I have the worst luck with these gacha draws too.
Since I started playing I must have spent well over 300k gacha seeds and so far I've only got a whopping amount of 3 four star girls
My personal rate for pulling 4* is around 1 out of 1000 rolls (0,1% chance - almost as hard as drawing a 6* from premium gacha )

*** Updated ***

I'm pulling 4*'s pretty often from normal gacha which in return drains all my luck for the premium gacha, I can never pull a 5* there..
