I didn't realize anyone worked in DBid order; I've usually gone by file size (digits) order. I should have posted an explicit reservation, but figured there were enough numbers ahead of where I was to serve as "canaries in the coal mine". I'm currently working on ID 1100000000328403064, (2^10613*75+1)/145019, with 3192 digits, and almost done with Phase 1 (currently at 7445 digits, should be done with Phase 1 today, and overall, at the latest, when I get home from work Tuesday evening). I'm very impressed with the size of the PRP backlog (5 numbers under 3k digits as I write this, only one over 1205 digits).

Did all 47. Now taking DBID's 1100000000803680471 and 1100000000803682766, 1849 and 2161 digits.
If there's a better place for these reservations, by all means let me know.

And taking all 28 below 2k digits. On my ancient laptop, above that starts taking a significant part of a day.

And done, though several, including the two biggest, got poached
There is now only a single PRP remaining below 3k digits.
