One, you don't practice PR. You do it or you don't do it.
Is there anything wrong with just PRing 10 books a day? NO.
I would caveat your efforts and remind you to approach it with a Beginner's Mind. Check your material for exactly what that is and then decide if you want to do the 10 books now.
Don't let the PRing 10 books a day reduce the rate you progress through the course. Once you've finished the course you should NOPS the PRWMS and then do the course again.
You are perfection.
