Since this is an appropriate topic, I'd like to share some additional info on EPx1 using orbs.
Because of a recent (unavoidable!) bug with activities \ missions I created this test account to try and amass a number of orbs and subsequently test EPx1 spins. Unfortunately I didn't have much time yesterday and now it seems the bug is already fixed, thank goodness. Due to this I was unable to get a very large number of orbs, say a thousand or two, what I got was around 200, which IMO is still, more or less, a decent amount.
Now the sad and disappointing fact was that the spins spawned girls only 4 times in 200 tries. A more or less certain (0.95) probability of this happening correlates with the girl spawning probability (in EPx1) closer to 2-3% than 8-9%. Again I didn't manage to try 1000 spins or more so the error from this setup is higher than expected.
