why the rush?To enter ch2, you need to:
Use 176 KPs
Clean 10 provinces.
You get 10KPs from the start and 80 for cleaning 10 provinces, so that leaves 86KPs or less than 4 days to gather enough KPs to enter ch2.
So unless someone mess up with goods production (having too low manufactories for example) or deliberately stays in ch1 (realy not sure why), there is no reason why someone should stay in ch1 for more than 1 week.
