Hi Sam Chen,
You raised a good question.
But in RHR theory, we encourage the students to do parallel study? That means the students study different courses at one time, therefore the CP for each course doesn't raise that fast. Actually we limit theCP raising rate of 20% per study session for each part.
We believe skill acquisition needs practice and repetition. That is why we don't allow the students to reach 80% CP in a short time.
