Oct 1 is used by your first guess. Therefore the dates for your 2nd and 3rd guesses are being ignored. You must wait 60 days before guessing anymore dates. At that time you may only guess the date, you can't update the number.

The 2 outer lines were upper and lower bounds (until firejuggler came in and guessed all 3 above the upper bound.) The box represents more than half of the guesses. And I ignored the most pessimistic guesses for this. In the second I re-assigned the dates and guesses, such that the lowest guess was paired with the earliest date. Graphed with a nice trendline for your pleasure. Attached Thumbnails

I'll revive my previous guess of 282,362,693 on March 3, 2025. And yes, it's another p=1 (mod 4).

I left these off the charts:
258150181 March 12, 2052
402143633
and these had no date associated with them, so they are not on the left plot:
87885437
87946949
