Here's something I noticed in my game as England in the GC. I failed several times to initially colonize some provinces in North America (notoriously Connecticut, Massachutsetts and Appalache), despite 70% or better chance of success. They did have resident natives, all low or very low aggressiveness. So, of course, I didn't want to kill them off. However, I discovered that, after frustration mounted, killing off the natives increased initial colonization to the 85% range. Other NA provinces didn't seem to have this situation.
I wonder if there's hard-coding to make colonization more difficult (or ban) than the % given in some provinces until the natives are eliminated. Not complaining, mind you, just wondering.
