i guess, but what about co-ed groups for example?
anyway, this actually did get me thinking so i crunched the numbers. we have 244 bg rares vs 218 gg rares, and then 6 co-ed rares. 53% chance for bg's being added to the raffle vs 47% for gg's, i think that's reasonable tbh. when you analyze the raffle results like you have then it can seem unfair, but a script that randomizes a bunch of artists without knowledge of the genders attached to those artists can't be biased when the odds are pretty much 50/50.
humans are just wired to look for patterns, so no matter how many different raffle pools we add and how we split the decks it will never seem balanced because we'll keep finding patterns. for example, soloist kang daniel has 4 legendaries out while other soloists like wendy and yongguk who were released in the same rare batch don't have a single one. it seems awfully suspicious right? but the program doesn't remember which artists it pulled in the past because it's not tasked to keep track of that information, and it doesn't know the relation between the kang daniel cards because they're all stored without a defined relationship, under completely random numbers. the generator just happened to land on those exact numbers that we labelled as kang daniel cards.
sure, but then how would separating bg and gg improve randomization? if the gg raffle then appears to favor certain gg's over other gg's should we start separating the groups by member amounts as well? how do we decide that it's fair?
