I find it hard to find any clear patterns in my data:
Here I show a sample of my data. It is my data from area 5-3. You can see if you can find pattern I did not see.

Normally when I do not have holidays, I lock in at 6:00, 7:40, 17:30, 20:00, 23:30 so data from many time periods.

My data from area 5-3 summarized.
C 133 times
P 65 times
G 130 times
E 113 times
N 806 times
L 2 times
Sum 1249 spins

C 10,7%
P 5,2%
G 10,4%
E 9,1%
N 64,6%

Spot layout:

1 2 3
4 5 6

I always picked girl in spot 2. It have been best spot in other test.

Number of N,R and SR-girls seen in the 6 spots:

Spot1: N-Girls: 107 R-Girls: 26 SR-Girls: 0
Spot2: N-Girls 97 R-Girls 33 SR-Girls: 3
Spot3: N-Girls 104 R-Girls: 20 SR-Girls: 9
Spot4: N-Girls 103 R-Girls: 26 SR-Girls: 4
Spot5: N-Girls 99 R-Girls: 30 SR-Girls: 4
Spot6: N-Girls 99 R-Girls: 30 SR-Girls: 4
Sum N-Girls 609 R-Girls: 165 SR-Girls:24

Procentage of girls seen that are: N, R and SR:
N-Girls 76,3% R-Girls: 20,7% SR-Girls: 3,0%

(In N-Gacha around 1.5% of girls are SR. 3x Chance seems to have around double SR chance as a N-Gacha)

N=Nothing
E=3x Exp
P=3x Pero
G=3x Gift
C=3x Chance(R spots that have rare girls, RS: spots that have SR-girl)
C(R:5,SR:2) = Rare girl in spot 5, SR-girl in spot 2.
L=3x Level

C(R:5,SR:0) = Means photos shown but no SR-Girl. Happened once.
If there are a SR-girl photos are always shown.

20 More spins at bonus stage:
1x triple Exp
1x triple Gift
1x triple Chance
17x Nothing

This data fit perfectly with the data I already got.

At this speen it will take 18 * 20 =360 spins = 3600 Stamina just to finish all Chance quests
Players get in 24 hours just 1440 stamina. So players need tons of luck to finish all Chance quests without using items at bonus stage.
Unless data sudently change Bonus Stage Suck big time.

I looked at the data from many1000s of spins I have recorded so far.
I cannot find any proof that chance change over time from large data sets.
In the end it is just pure luck. From time to we all got a good day.
No spots are better for picking than others long run.
Players get proximately the SR-girl 1 in 6 when one of the 6 cards is a SR-Girl.
Human seem to forget (ignore) loose easily but remember wins.
This might help to explain why so many loose so on much gambling – They feel they really win-ing but they are in fact losing. People look too closely will find patterns.
I found them many times – each time I made a theory and the started to collect new data to test it.
So far all my theory about some spots to be better or game to be anything but just random have failed.

I might be wrong but that is what data tells me so far.
I would be happy if anyone could prove me wrong.
