Ok fair, maybe 7% was a bit low, but lets say its even 25%. The chances of me not hitting that girl while she's at 25% in the next lets say 25 battle are REALLY low. Unless of course the system is rigged and 25% chance is actually like 5% chance cause it favours the lower amount.
A ceiling should honestly happen as well. I am literally sitting on 1000 silvanus battles for just 1 girl. That is ridiculous.
