Well, I'll tell you a secret. You can use CP as soon as you cut it. It's soap. I wouldn't sell it until it's cured for at least a few weeks but for personal use, I use it straight away. The longer it cures, the harder and more mild it becomes but once it's soap, it's soap and I personally have never been able to wait to try a new batch so as soon as it's hard enough to cut, I slice myself a sliver and enjoy
