Decided to math out wordz of main story posts. (Not paying super-close attention to the data, automation is supposed to save time!)
(Large table elided)
The shortest chapter (omitting interludes, omakes, PHO segments) is, oddly, chapter 1. The longest chapter is 246.
Words/day statistics: min 61.7, median 2750, max 23700, with 29100 as highest posted on one day (246 and its incident report).
Chapter-day interval statistics: min 0 days (remember when two a day was normal?), mode 1 day, median 2 days, mean 5.7 days, max 159 days²90 days.
²oops, canonized guest omake got slotted in months after its ordering.
So, according to these statistics, the next story post could optimistically be as soon as Apr 2, 2021 with as many as 23700 words; it is expected on Apr 8, 2021 with 6247 words; and at the most pessimal should appear at Jul 1, 2021 with as few as 5561 words.
