Registrations over time

Requests vs registrations

Estimated renewals over time (request >180 days after previous request)

Sign-up testing bursts (several requests in the first days) are excluded; only gaps over 180 days count. "Estimated" because only Apple can confirm an actual renewal, so true counts may differ.

Renewals due vs estimated renewed (yearly, all time)

Each prior-year request is assumed to produce a certificate coming due 12 months later (an upper bound on what's due), so the implied rate is a lower bound. Full years only.

Repeat-request profile (registrants by max gap)

The <2d spike is testing noise; 180–400d matches the expected annual-renewal pattern.
