Woah a 180-190k debut is pretty good stuff
Album sales (digital/physical/vinyl) have
decreased a heap in recent years. In the US, ARTPOP debuted with 258k copies sold late 2013. In 2014, US album sales declined 11.2%. So if it was released Nov '14, you could hypothetically say that it'd have sold 229k copies. In 2015, US album sales declined again by 6.1%. Take that off the 2014-hypothetical-debut of 229k, and you get 215k. In 2016, [based off mid-year reports] US album sale have declined a whole 13.6%. Again, take that off the 2015-hypothetical-debut of 215k, and you get 185k. To reiterate, that's about where you could estimate ARTPOP would debut if she released it under the same circumstances this November. Let's spell it out:
2013 ARTPOP 258k
2014 ARTPOP 229k (subtracted by 11.2%, rate of aggregate album sales decline in that year)
2015 ARTPOP 215k (subtracted by 6.1%, rate of aggregate album sales decline in that year)
2016 ARTPOP 185k (subtracted by 13.6%, rate of aggregate album sales decline this year [based on Q1/2])
So this is debuting right where ARTPOP probably would have if it were released today, but with a fraction of the televised appearances or performances [she's literally had 2?], without a single on radio (ARTPOP had 2), minimal-to-no worldwide promo at all, and far less commercial material.
