In the beginning Rapid Read a few of the books you activated that you felt you got everything you need from.
It provides a scale against your experience. How much did you miss. Would one more activation pass have found it. Was it really worth the extra time finding that one thing you missed (if any).
It helps you identify if you're short changing yourself on the activation step or spending more time than necessary. So while rapid reading is not necessary, it can be useful as an indicator how your activation is going.
