If it is worthwhile PRing a 4 page text, then i'm figuring that it is not a necessity to wait 20 minutes before activation. Also, in class we are sometimes instructed to read maybe a 10-15 page essay. I was just wondering if it would be feasible to PR these while surrounded by others. Would the environment be to distracting? Or would it depend on the person, if the individual could get relaxed while in a group. Anyway, thanks for your responses .
