Do as you like. That's the good thing about the Photo Readind Whole Mind System: You choose what steps you apply and when you apply them.
And, in my opinion, Rapid Reading is activation. It is just seperated as a single step because it is most like normal reading.
As I see it, everything you do with a text after photoreading it, is activation - if named so or not.
So, RapidRead first and later, when you need specific details out of the novel, Mindprobe and/or Superread&Dip.
Hope this helps,
