And if your rolls are duds, or you get good rolls but for a different element, then you might've been misdirecting your farming.

So I'm a bit tempted to roll for Hastur, knowing that I'll have more jewels when Cybele releases. Is this wrong?
This is a mathematical problem with an optimal solution. More options for 'hits' doesn't necessarily equal better odds, as inbetween Cybele and Seth are kamihime of other elements, which can be considered 'misses'. So if the number of misses added is proportionally greater than the number of hits, you're better off rolling earlier.

You can actually calculate all this using the Gatcha calculator in my Toolbox.
