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.
