[Undescribed Horrific Abuse, One Victim & Survivor of Many]

daydream re-attempt:
we have ratelimit_count total queries available in the last ratelimit_period
and we want two of the queries to have set times: eta and eta - min_period
[we can in theory count the queries we have made in the final ratelimit_period.
 this gives us a number of queries remaining we have.
 maybe ideally, we would time them so that third-to-last precisely
meets the second-to-last.]
[other branch of daydream:
 instead of summing them from the large end, where we can overrun if
the integer shift changes from delay, we could sum them backward from
the small end.
 that is, we would plan on the future times, and pick the time that
provides for them.
maybe we could try an example.
