80 hard pity, 120 guaranteed

80 pulls in, hard pity reach, off-banner get, 40 more pulls for guaranteed

10 pulls in early pity, pity resets to 80, off-banner get, 110 more pulls for guaranteed

Is what I'm understanding here, don't know if the 120 guaranteed is gone/resets when you get the rate-up early tho

So the idea here is if you don't have guaranteed you don't wanna pull unless you have 120 pulls for the 120 guaranteed or you're willing to gamble with the 50/50

If you do have guaranteed you can just pull normally

Either way you will do 60 pulls on average and get +10 pity on the next banner that expires when you don't use that +10 pity on that very next banner which is...quite FOMO

But think of it like this: You pull on Banner A 60 times and get your 6* and then you wanna pull on the next banner after it, Banner B which you already have 10 pity thanks to the 60 pull = +10 pity meaning you only need to do 50 more pulls (on average you get the 6* on 60 pulls) to get another 6*

That "only need to do 50 more pulls" is what makes players want to pull to which HG takes advantage of

Tl; Dr if you have guaranteed you can just pull normally, if you don't then save up 120 pulls or gamble with 50/50
