Re: Pero Pero Saimin
so to clarify the refresh trick: using the refresh trick will only give you the possibility of gaining 2 additional cg images to appear, no matter how many times its used. a reveal card is not lost when the refresh trick is used, but instead is automatically used, revealing the previously revealed cards. meaning even if additional cg images appear, no changes to which cards will appear will be made.
= Just don't use a reveal/open card item unless it goes to 5 cgs in the first place from refreshing after using a gacha ticket that originally shows 1-4 cgs.
I don't think that the cards ever change with the refresh trick, I think it just more accurately (super accurately, lol) shows your chance at one of the 6 being an SR. I think 1 CG is 20%, 5 is 100% (Just guessing). So it originally showing only 1 cg still has a very small chance of there being an SR in the 6, but using the trick to change that 1 cg to 5/0 cgs makes it a lot safer obviously to know when to use an Open/Reveal card item. So when you spin a gacha, it seems to me like it already places the cards you can get before you flip them basically, then it spins another roulette that is the cg amount shown that gives you an approximate chance on finding an SR in the 6 cards shown. Using this trick just spins the SR estimation roulette again, I think.
Most of this is just speculation since we can't see the code, but experimenting a bit with this refresh trick makes me think that the system is actually pretty fair. Sometimes I wonder in games like these that are so easy to lie to the player if they don't just spawn your reward only after you choose a chest/box/card/etc, so they can control what you obtain and lie about your chance to obtain rare things. Of course they could still shift the cards around after you choose a random one, but that doesn't really matter thanks to Open/Reveal cards.
