The droplist is most likely complete and contains all
domains that will be released at the specified date.
The pending delete enddate (dropdate) can't be determined correctly.
Domains might drop earlier or later.
It is best to consider the enddate just a guess!
It is not clear when exactly a domain drops. It does seem to vary mostly between
whois free-date and whois free-date +8days, but some domains drop even later.
There are domains with free-date 4 years ago and they still have not dropped!
Those are however rare. Currently the free-date is being used as the dropdate in pending delete.
All domains with dropdate <= today will be checked every day and if available moved to deleted .ru domains.
If they did not drop, they will be checked again the day after.
There are days and sometimes even weeks without deleted .ru domains!
Additionally the deleted domain list on cctld.ru is imported once per day.
