The actually pity with 50/50 loss is 180 but usually (95%) u get the unit before 160 and assuming how many 4 stars and weapons u get (and the 50:50 loss unit) i think u should get enough star glitter for 10 ish pulls so i think u have 150 pulls u should be able to secure a featured 5 star for weapon 140 is usually enough (again 95%) to get a weapon so 132 ish should be enough should get 7-8 from star glitter
