I numbered the 6 Cards spots this way:

1 2 3
4 5 6

I recorded how many time the SR-Girl was in each of the 6 spots:

SR1: 3 times
SR2: 5 times
SR3: 6 times
SR4: 6 times
SR5: 4 times
SR6: 6 times
Total 30 times I saw 1 SR-Girl.
I would expect 30/6 = 5 times to get the SR-girl . I got her 4 times. Last gave I tested I got more SR-Girl then expected.

No spot seems a lot better than the other spots.

Same for R-girls:

R1: 54
R2: 50
R3: 39
R4: 44
R5: 52
R6: 46
Total 285 R girls seen.
Expected R-Girls got 285/6 = 47.5 R-Girls obtained 57.

Total 229 Chance spins.

If you dont use items chances seems to be around:
N-girl 78,5%
R-girl: 20%
SR-Girl: 1,5%
