Although since I brought it back up it now updates 55 sequences twice per hour (haven't bothered updating the page), I do believe the 3.5 day cycle time to refresh each sequence is the likely cause of this apparent discrepancy. You are indeed free to reserve any other sz 120 sequences as they appear :smile:

Do you mean, if a sequences has not gone through an update/refresh cycle, then the reservation may not get posted in a timely manner?

All reservations are updated every time the script is run, i.e. every half hour (up from the every hour I used to run it at). Only 55 sequences are updated from the FDB every half hour. That means that every sequence is updated approximately once every 3.5 days, even though all reservations are updated every half hour.

So what I'm suggesting is that yoyo may have indeed reserved all the sequences my website reported at 120 digits, but since then either a) some sequences got updated size information and became size 120 after he reserved what he could, or b) that the sequence was indeed up to date at the time of his reservation, but his since made further progress making it size 120 (e.g. downdriver run and then abandoned by its previous reservee at 120 digits).

While the date of the most recent update for each of the sequences in question would fit, a lot of them haven't had any progress for months if not years.
