Need Help to Interpret This Document

[Propfam 2,286]

Hello,

I'm struggling to get hi-rise buildings in a city. The city is reserved for I-HT and R$$$ because the neighboring ones are R$ city (You know, R$$$ for some reason doesn't like R$. Pollution maybe?). Since I-HT takes up lots of space, I can't build lots of R$$$ lots. My regional population size is 2.5 mil. Why I can't get hi-rise buildings in my fresh city? I found this document: https://www.sc4devotion.com/forums/index.php?topic=3578.0. But, there are some questions:

1. Take the Residential Stage Limits section. There are R$, R$$, and R$$$ values. What's the meaning of

   The threshold values are in all cases the total regional residential capacity (not population): R§ + R§§ + R§§§?

   Is it meaning that I should add R$, R$$, and R$$$ of a row? For instance, the last row. It means I should add 3085020 + 3469411 + 3856275? Or, should I have 3856275 R$$$ capacity in my region? Or, should I have 3856275 total residential capacity to have stage 15 of R$$$?

2. What's the meaning of percentual chances? Is it works like, for instance,

   I have 1,000 lots of buildings and reached the last residential threshold on the list. It means I have 90 lots (or 9% of total lots) that are Stage 15?

    

Help are appreciated. Thanks.
