What
When you are rate limited and no known reset time is available, the banner computes a projected time, but only for accounts whose low-priority-offer experiment arm is set to "treatment". Everyone in the control arm sees the previous behaviour, with no time shown.
Details
The projected value is used only when neither an active rate-limit phase nor a known reset timestamp supplies one.
The arm value arrives from server-side configuration, so nothing in this build decides who is in it.
