Core creation cost and time

[Rexos]

Right now, what is the cap for the CCR? Is it 80 or 90?

And then I'd like to know why this happens...
Just out of curiosity, in Herat I have 83% CCR and it takes 6 months, while in doab I have 98% and ti takes 8 months....why? It should be the opposite

What's your primary culture? It takes half the time to core provinces of the primary culture group (but doesn't affect cost at all).

Edit: Promoted cultures take 25% less time and to answer your original question, it is capped at 80.

From memory the caps for time and cost are different. One is 80 and the other is 90. I believe 80 is the cap for coring time. The province that is taking only 6 months gets a further discount from culture.

Edit: bly's post below is more detailed and correct

Khorasani is in your primary culture group.

Upper Doab: .26*36*.9 = 8.4 months coring time.
Herat: .25*36*.9*.5 = 4 months. Coring time floor is 6 months.

Coring cost cap is 80%. Both permanent and normal claims reduce coring time by 10%. Coring time for cultures in primary culture group gets reduced by 50%.
