the poly translate to 180
you have 10
and 10 already rolled
long ago i calculated that the all weeklies etc considered, we get around 1 roll a day, events excluded
that leaves you with 1 month for yuzuha, 1 for alive and 1 for orphie. so 3 months = 30 rolls
even though it says 90, you really only need 80 for the S because of how the rates go up
your total so far is
180+10+10+30 = 230
statistically you will win 1 50/50 and lose the other
so the cost of 2 banner characters is 160+80= 240
and then the engine is a 75% chance, so most likely you'll get that one, but it's still paying out at 80

statistically, around 2 banners reach the max of 80 before you get an early S drop
so taking the event poly into account, and that you get statistically lucky, yes, you would have enough
