vpao3

short pre-cutover

An app start too short to pin down a seed. Some have candidate seeds, listed on their pages; their counts are plotted by draw with the draws numbered from the first post (an assumption).

Draws
Not known: no seed was found, so the posts are numbered from the first post, at draw 0, as consecutive draws (an assumption; the 2012 build starts at draw 0, the 2013 build at draw 1 after its startup draw)
Posting interval
60 min
Schedule breaks
1 (gaps off the interval in force that are not a cadence change; a burst under a minute is not counted; marked in the table below)
Title clock
UTC−7 at the first post (the time zone the post titles are written in; it changes 1 time, marked in the table below; a daylight-saving shift of the same zone is not counted)
Started
Wed 2012-06-27 12:07–13:07 Pacific (estimate: within one posting interval before the first post)

Notes

Possible seeds

No seed fits this run under any model tested. Unlike the other short pieces, it has enough information (seven values of range 45 or more, about 40 bits) that a matching seed would stand out anywhere in the search space. None exists under the count model that explains every placed run, so something about how these values were drawn must differ.

The run

Seven posts, 27 June 2012 at 20:07 UTC to 28 June at 01:11 UTC. The first is 20 minutes after the last post of run 08, and then the posts come hourly at about :11. The title clock is on UTC−7 for six of them and on UTC−4 for the last one. Run 09, the first run with Next(8, 64), follows about 30 hours later.

What has been tested

Test Model Space Result
Full search Next(8, 64), one draw per post, up to one skipped draw, up to eight extra draws, offsets up to 72 every seed 0 matches
Continuation Every placed count stream, each with its own range the first 20,000 draws, up to three skips 0
Continuation of runs 1 to 8 Any Next(lo, hi), lo 0 to 14, hi 53 to 128, up to nine draws between posts the first 3,000 draws Run 08: 0. Runs 02 and 06: six chance paths, none consecutive
Fresh start 1,140 ranges (lo 0 to 14 by hi 53 to 128), up to two extra draws, offsets up to 72, launch between 12:00 and 20:07 on 27 June the two June boots 5 hits against 5.6 expected. Controls found 3 of 3 in 20 batches
Own GUID seed One draw of each post's own GUID-list seed, the same draw and range for all seven seven known seeds 0

An empty result means something here. If the model were right, the true seed would appear in these searches, and at about 40 bits chance matches are few: about 0.09 for the narrowest test and about 1.6 for the broadest. So an empty result rules the model out. The five hits in the fresh-start test all sit at implausible starts (offsets of 25 to 62, or two samples per post). None is at draw 0 with one draw per post, as every 2012 run is.

Open readings

What could decide it

A model change that also explains another unplaced piece from June or July 2012, such as vvjmg or the burst in vsb-burst. On its own, this run cannot select among the readings above.
