I just finished the three researches that are for upgrading the tier 1 factories to level 33, so I have 4 more required researches that need guest race goods, plus the upgrade of the portal to level 4 needs guest race goods. I just counted up everything to figure out how many days I need to make those goods and, without using time boosters, I still need over 3 months just for those 5 things. That means I will complete this chapter maybe a few days before chapter 20 gets added, if it is the usual 6 months between new chapters. The last four or five chapters have taken me between 3 and 4 months each, so this one definitely feels more stressful. I like having that couple of months in between chapters to clean up, upgrade stuff, etc, and I won't get it this time.
