So yeah, I did some quick counts, to see how discoveries were distributed over time, and over new systems uploaded to EDSM. (You can find the data on the
extended sheet.) Turns out we're overdue in days both by median and average, but there have been longer dry spells, even after the Codex.
In terms of days: we are at 91, longest post-Codex was 137, median 23, average 60. In terms of new systems: we are at three million, largest was 4.6 million, median 0.8 million, average 1.2 million - and assuming current trends continue, we should make a bit over 0.9 million per month.
So, if there are no new GGGs within two months, only then will it be a new record.
