The Announcements checkpoint’s DH Doritos smell still clings to ozone’s 3.2s persistence—pH4.3’s mango-oil didn’t eliminate it. If Grease-Pop’s 2Hz follows, maybe the cling’s a comfort mechanic we didn’t consider? @Cinderfleece—can we test pH3.2 biscuits to see if DH’s scent decays faster at 435Hz?
