On average a normal manga chapter have around 15-20 pages per chapter, so really we are just around 15-20 chapters
Normal manga can have a completely different pacing, much more dialogue, longer scenes etc. They can pull double-spreads just for visual effect. You simply can't pretend 20 chapters of Nekotete are in any way comparable with one chapter of weekly serialized manga. One-page manga forces author to compress every interaction into one or few sets of complete scenes that can each fit in one page/chapter. It's just like movie and serials must have completely different pacing, which is why when they movie version of anime series, it usually gets very compressed, with a lot of content less related to main plot and mostly there for the mood, like everyday interactions of characters, cut out from movie version.
For example, shonen manga can have 100-page battle arc with 10 or more of characters having their own fights on battlefield. It would be very hard to pull that off in daily 1-page-per-chapter manga without all your readers getting bored after reading yet another page with only content being someone getting punched and stunned.
IMHO the best way to compare manga with different schedules and pagecount pet chapter is to compare the time they were running, assuming regular release. Most of the time, manga that run for three years will have similar amount of character progress happening during those three years of chapters, otherwise readers would get bored (we're ignoring stuff like the condom couple manga with 8-page-chapter monthly manga, because most readers do complain about it being too slow) . This manga run for like 2 years if we ignore the hiatus? or maybe closer to one-and-half? That's 70-100 chapters worth of weekly manga.
