Gosho's dramatically decreased his output since December 2017, so ZTT could more rightly be seen as a substitute for Conan, a "product" which is in short supply these days. Like how people started using chicory instead of coffee beans during various wars due to coffee shortages and yet people are still drinking crazy amounts of coffee today. If anything, the fact of ZTT should serve to keep people interested in Conan during the long hiatuses.
The basic misconception that ZTT is Conan's substitute is something stemming from the fact that ZTT and Conan trade places in SS. But if I logically break down your example, the chicory was used as a substitute of coffee not the substitute of Fired Rice. Conan and ZTT are two different series, ZTT focuses mostly on raising Amuro fangirls, and just throwing main plot/Conan characters to stir the interest of Conan readers.
From the sales disparity it's evident, even if all Conan fans are gobbling up ZTT(that's another assumption, it would be a great study if Kor goes on doing a survey regarding Conan fans who follow ZTT with same enthusiasm and whether the break-up is uniform in all age and sex groups.) there are plethora of ZTT fans who are not Conan fans.
So here is the catch 22 situation. You must be aware of the 80-20 rule. 80% of your business is generated by 20% of your products. But the if the 20% of the products exclude the talismanic product of the company it's a very bad sign for that talismanic product.
The situation here is comparable to Apple. Apple was a PC making Company but when their Smartphones generated more craze and pushed up revenue it bacame synonymous with i-phones and i-pads, not with PCs.
If it goes on like this Amuro will gobble up Conan. So it's a good idea for the Manga business, but a bad idea concerning Conan.
