I'm not sure I understand what "study -> study" is. Is it studying without creating flash cards, or utilizing them? As in just studying the book, doing problems, etc?
If so, in my experience, then yes, integrating flash cards is much more effective. Especially for working professionals who often have to step away from what they are studying for many months at a time (except doing the cards for 15 minutes a day).
